Technical field
The application relates to radio communication device.More specifically, the application relates to the system including radio frequency (such as: the microwave) antenna for high-speed remote radio communication, and particularly relating to device, these devices include for making wireless communication system electromagnetic signal selective attenuation, to improve the parts of signal quality.The application further relates to for protecting wireless communication system to exempt from injured device.
Background technology
Fast development along with optical fiber so that distance and high bandwidth transmission are possibly realized, has reformed communications industry and has played dominant role in the arriving of information age.But, the application of optical fiber has its limitation.Owing to optical fiber arranges the initial input requiring huge time and materials, therefore by the region of Fiber Optic Extension to sparse population, such as rural area or other outer suburbs being difficult to arrive just are not calculated very much.Further, if to set up point-to-point connection in multiple places, new optical fiber is laid also infeasible economically.
On the other hand, wireless transmit communicator and system provide the high speed data transfer by Air Interface so that it is become the attractive technology of one of the area offer network connection not yet arrived for optical fiber or netting twine.Radio communication passes rapidly through atmosphere and space by electromagnetic signal, generally arrives another root antenna from an antenna.But, the wireless technology that the electromagnetic signal for remote, point-to-point (or single point-to-multipoint) feasible at present connects runs into a lot of problem, such as limited bandwidth, relatively low signal quality.

Isolation chokes frontier district may relate to be arranged on the structure of shield region or part, or form entirety with guard shield sidewall, for decaying or weakening from antenna (such as, transmitting antenna, reception antenna, transmit/receive antenna) electromagnetism overflow, mail to the unrelated signal of antenna thus reducing.When (such as, pass through guard shield) is installed on reflector in isolation chokes border, and antenna sends or receives ELECTROMAGNETIC RADIATION SIGNATURE, can decay or weaken and mail to or from the electromagnetic radiation of antenna in isolation chokes border.Therefore in certain embodiments, choke for antenna system can include guard shield, this guard shield includes the sidewall of bending, sidewall surrounds central axis, sidewall connects the first end and second end of guard shield side by side, this first end and the second end can allow electromagnetic radiation pass, first end of guard shield may be installed on the forward direction opening of antenna reflector, for assembling electromagnetic radiation to antenna, forward direction opening is used for receiving electromagnetic radiation, after installation, the forward direction opening that guard shield is set to from reflector distally extends；Chokes border is arranged on guard shield and is positioned at sidewall outer, and when guard shield is arranged on reflector and antenna sends or receives electromagenetic wave radiation, this chokes border is sent to for decaying or from the electromagenetic wave radiation of antenna.
Isolation chokes frontier district can also be isolated gate described herein, isolation boundary, chokes, chokes border, isolation chokes, chokes grid etc..Can there be the structure (including ripple struction) of multiple barrier, such as crestal line, it is possible to weaken the cross-talk sending between parabola antenna disk and receiving in chokes border (such as, isolate chokes region).These crestal lines have suitable height/depth and spacing, it is possible to isolate the specific frequency range (such as, bandwidth) that this equipment uses.Such as, grid structure defines the degree of depth isolating chokes border or depth bounds concentrates on the 1/4 of the bandwidth wavelength used, and this is described more detail below.Functionally, when antenna is when adjacent parabola sends disk and parabola receives between disk, isolation chokes border can provide the isolation (such as, 10dB isolation) more than lowest level.
Isolation chokes border (also referred to as chokes, chokes border or isolation chokes) may generally serve as the barrier between two (or more) antennas or baffle plate.Such as, isolation chokes border can as the barrier between transmitting antenna and reception antenna.Chokes border may be used for suppressing the propagation of wireless wave, and the frequency of this wireless wave is greater than or equal to 9GHz, and less than or equal to 41GHz.Multiple deformation of the wireless device of the application may be used for operating frequency bandwidth near 5GHz, thus chokes border can include a plurality of (such as, more than 3, more than 5, more than 6, more than 7, more than 8, more than 9, more than 10, more than 11, more than 12, more than 13, more than 14, more than 15, more than 16, more than 20, more than 25 etc.) spacing crestal line separately.These crestal lines can be parallel to the outside frame of guard shield.These crestal lines can also be parallel to one or more parabola with chokes.As a rule, the crestal line that includes of isolation chokes border extends along the height of the plane (and be perpendicular to parabola antenna, its correct position is equipped with guard shield) being perpendicular to guard shield end points (opening).These crestal lines (can also be overall) at least partly extend along the periphery of shroud encircling or the second end or shield distal end.These crestal lines (can also be overall) at least partly extend along the frame of shroud encircling or guard shield the second end or shield distal end, and so these crestal lines are perpendicular to the plane of shield distal end.Spacing between the height of these crestal lines, adjacent crestal line, the quantity of crestal line, the shape of crestal line and the length of crestal line can optimize based on the specific electromagnetism bandwidth (such as, wireless bandwidth) used.Such as, chokes border can Optimization Work frequency in the bandwidth of about 5GHz, so, this device signal between transmitting antenna and reception antenna is isolated more than 70dB.Shown choke elements can will improve the isolation (such as, isolation of about 12dB etc.) of 10dB.
In certain embodiments, isolation chokes frontier district is formed by multiple layer metal (strip, lamellar etc.), or other approximate materials, setting adjacent each other (combines), replaces some layers, thus form multiple crestal line and raceway groove in these layers combined.Such as, in a way, chokes limiting bed can pass through to be layered bar, rib or other similar structural groupings together into, then the structural bending of this combination is become the curved surface (such as, in order to be arranged on the edge of parabola antenna and/or guard shield) wanted.The material of these multilamellars can be fixed together in any suitable manner, including glued joint (such as, by resin or epoxy) and/or fixed by screw, grappling, fastening, riveted joint, or other similar fashion.
In use, when second (such as, parabola) antenna close to the first parabola antenna time, and the first parabola antenna and chokes guard shield connect, when the second antenna is adjacent or near first antenna and chokes guard shield, first antenna can more effectively with the second antenna isolation.As a rule, isolation chokes frontier district can be arranged between the opening of first antenna reflector and the second parabola.Although the concrete condition being to use parabola described herein, non-parabola (can also substitute) use.
Such as, for the wireless transmitting system of wireless signal, it is possible to including: the first reflector；For sending the radio-circuit of radiofrequency signal from the first reflector；Guard shield with the first reflector connection；And and guard shield connect isolation chokes border.Wireless system can also include the second reflector, and isolation chokes border, the overall signal isolation that this isolation chokes border is used for improving between two parabolas (between two parabola antennas).Such as, the overall isolation of the radiofrequency signal between the first parabola and the second parabola, including the isolation provided by isolation chokes border, the isolation of this overall signal can more than 10dB, 20dB, 30dB, 40dB, 50dB, 60dB is (such as, more than about 65dB, more than about 70dB, more than about 75dB, more than about 80dB etc.).Such as, the overall isolation of the radiofrequency signal between the first parabola and the second parabola, including the isolation provided by isolation chokes border, it is possible to more than 70dB.
As it has been described above, isolation chokes border can also include crestal line.These crestal lines can extend along the length direction (such as, the direction of the outside frame of reflector) on isolation chokes border.The height of these crestal lines can be the same or different.In some deformation, the height of these crestal lines can change.Such as, in isolation chokes border, adjacent crestal line can be separated by raceway groove；In some deformation, the degree of depth of each raceway groove can more than the width (distance) of adjacent crestal line.The degree of depth between raceway groove can be consistent, or different；In some deformation, the degree of depth in a raceway groove also can change.
Such as, isolation chokes border could be arranged to extend along the curved boundaries of two adjacent guard shields or parabola, and can include a plurality of crestal line adjacent to each other；These crestal lines can according to all long arraies of the two of parabola opening.Chokes border can also be set so that substantial amounts of crestal line arranges along sine curve, i.e. the sine curve diameter through isolation chokes border is formed on the top of adjacent crestal line or bottom.Therefore, in some deformation, the crestal line on these isolation chokes borders arranges along sine curve.Can there be different section profile on all isolation chokes borders described herein on its horizontal section.Or, in some deformation, there is asymmetric rib height profile on isolation chokes border, therefore symmetrical it is not necessary to.
Therefore, as it has been described above, the crestal line being at least partially isolated chokes border can have different height；The crestal line that isolation chokes border adjoins can have different height and be separated by the raceway groove of different depth.These raceway grooves between the crestal line that isolation chokes border is adjacent can be separated from each other with the mark of some wavelength length.The degree of depth of these raceway grooves between the crestal line that isolation chokes border is adjacent can be the 1/4 of the mid frequency of the device used.Such as, device is applicable to transmission frequency signal between 5.4GHz and 6.2GHz, and the degree of depth of the raceway groove in isolation chokes border can about between 13.9mm and 12.1mm；For suitable in frequency being the device between about 4GHz and about 8GHz, the degree of depth of the raceway groove in chokes border can about between 18.8mm and 9.4mm.
In above-mentioned all embodiments, top view as shown in Figure 3A, choke can include only partially surrounding the chokes boundary member that guard shield sidewall extends.Fig. 3 A shows another kind of chokes part 34, and it can be arranged on antenna reflector as a part for chokes guard shield.Still in this embodiment, the same with other embodiments, chokes part 34 is chokes frontier district 34.Can there be any shape or direction in chokes frontier district, including shape described here or direction (such as, relative to the position on other chokes borders).Such as, chokes frontier district can include crestal line and raceway groove.These crestal lines can be identical or different with the degree of depth with the height of raceway groove.The part on chokes border can overlap with a part (beside portions) for guard shield, and so, the another part on chokes border may be located remotely from guard shield (as shown in Figure 2 B).
Fig. 4 A-4C is the chokes guard shield schematic diagram including antenna house.In this embodiment, chokes guard apparatus may be mounted on antenna reflector, and includes the chokes border surrounding or partially surrounding guard shield.Fig. 4 A is the schematic diagram of the chokes guard shield 4 having cylindrical shroud region (sidewall 8), and chokes guard shield can be attached at the near-end of reflector.Fig. 4 B shows the central axis 15 of chokes guard shield.This chokes guard shield includes antenna house 60.In figs. 4 a-4 c, antenna house covers the outside of whole distal surface, including the distal openings through chokes guard shield, and chokes frontier district 55.Chokes frontier district 55 is arranged on shield region (such as, guard shield sidewall 8) and above and surrounds this shield region.Although shown in figure is right cylindrical, shield region may not be right cylindrical.As described above, isolation chokes border can only have part to extend around the opening of guard shield or parabola.Such as, isolation chokes border can partly extend around chokes guard shield (or chokes guard shield of reflector).
Isolation chokes frontier district can along the edge of guard shield (such as, shroud encircling or shroud encircling end points) extend, or extend around reflector opening so that the angle of shroud encircling, protective cover end or reflector opening is less than 180 degree, about 30 degree to 180 degree between (such as, it is at least about 40 degree, is at least about 50 degree, be at least about 51 degree, it is at least about 52 degree, it is at least about 53 degree, is at least about 54 degree, be at least about 55 degree etc.).In all these deforms, isolation chokes border can be dangled on the outward flange of guard section or parabolic reflector wall.Such as, due to guard shield relative narrower, therefore can dangle on reflector and guard shield in chokes border.
Fig. 5 A-5C is the schematic diagram of chokes frontier district.In this embodiment, optical absorbing material (not shown) can be arranged on guard shield sidewall close to chokes boundary, but it can also be replaced and be arranged on elsewhere or be additionally arranged on elsewhere.Such as, optical absorbing material can be arranged on side or the far-end of chokes frontier district, covers all or part of shield region.Optical absorbing material can on guard shield or in guard shield, or on part chokes border, on such as chokes wall.Optical absorbing material may be used for weakening from or mail to the deviation of antenna or unrelated radiation, and this antenna is attached with chokes guard shield.
As shown in figures 5a-5c, there is the crestal line of substantial amounts of (such as, more than 3, more than 4, more than 5, more than 6, more than 7, more than 8, more than 10, etc.) chokes frontier district；The maximum quantity of crestal line is determined (such as, the diameter of chokes guard shield can have much) by the space holding crestal line.As a rule, chokes guard shield need to have about 3 to 40 crestal lines, i.e. 5-40 bar crestal line, 10-40 bar crestal line, 10-30 bar crestal line, etc..Fig. 5 D is the side view of chokes frontier district, and (or being integrally formed) can be installed on chokes region in this chokes frontier district.As shown in Figure 5 D, the height of these crestal lines is about consistent with width, and arrangement adjacent to each other with one heart.Fig. 5 E is from the sectional view shown in Fig. 5 D direction.
Fig. 6 is the chokes border schematic diagram of another embodiment, and this chokes border may be mounted on guard shield.In this embodiment, chokes frontier district is formed by the crestal line of a large amount of (such as, 7), and these crestal lines distally (central axis relative to chokes guard shield) extend different distances.Therefore, it is different that these crestal lines are likely to size, or adjoining dimensions, but is arranged in as shown in Figure 6 on song (such as, sinusoidal) face.
In use, chokes guard shield may be used for decaying from/mail to (such as, side is penetrated) radiofrequency signal of off-axis line of parabola.Such as, Fig. 7 is the side view of the antenna being attached with chokes guard shield.In the drawings, chokes frontier district is cut off, and is divided into the first chokes boundary member 90a and the second chokes boundary member 90b.Antenna house 89 may be mounted in the distal openings of guard shield.Antenna house is highly useful for protection antenna system.Other materials so that electromagnetic radiation (such as, wireless wave) traverse, but can be arranged obstruction by antenna house.Such as, antenna house can arrange machinery barrier to stop other materials, such as air (wind), animal, fragment, dust etc. enter antenna system (such as, entering chokes guard shield and/or reflector or the inner space determined by reflector).Antenna house can protect antenna system to avoid infringement.Antenna house can install (or being provided for installing) on guard shield with fixed relationship.Antenna house can be installed or be provided for being arranged on any position of guard shield.Such as, antenna house may be mounted at first end (near-end) of chokes guard shield (such as, it is provided for being arranged on the protective cover end of emitter), but more conventional situation is, may be mounted at second end (far-end) of guard shield (such as, and be not configured to and reflector 74 install protective cover end).As it has been described above, guard shield can install (or being provided for installing) in a position-stable manner on reflector, thus antenna house can install (such as, passing through guard shield) in a position-stable manner on reflector.Antenna house can cover the opening of part or all of antenna reflector or guard shield.O-ring can be used to ensure that antenna house safety on rear side of the edge of guard shield or reflector.Rear side and the antenna house of isolation chokes can be closed in the extension of o-ring.In some deformation of chokes guard shield, guard shield the first end is opening, and the second end includes the antenna house that is arranged on chokes guard shield, and when chokes guard shield and antenna house are arranged on reflector, the inner space determined by reflector for stoping material to enter.Antenna house can substantially over whole second end of chokes guard shield.Antenna element (such as, feed 77) in reflector can also be choked guard shield and cover.In some deformation, chokes guard shield extends along the opening towards far-end of reflector so that antenna house can be put down and be overlayed on feed.
As it has been described above, as a rule, the scale in chokes region, the quantity of such as crestal line (and raceway groove), highly, width, spacing etc. can optimize according to the decay of the characteristic frequency (scope) of antenna system.Such as, the degree of depth between crestal line may be about 1/4 of wavelength used by system.When antenna system is for sending and receive signal that frequency is 4GHz to 8GHz, the adjacent degree of depth between crestal line can between 18.8mm to 9.4mm (such as, center is near 13mm)；When antenna system is for sending and receive signal that frequency is 5.4GHz to 6.2GHz, the adjacent degree of depth between crestal line can between 13.9mm to 12.1mm.By the arrangement of these crestal lines, it is possible to make edge diffraction minimize and weaken the communication energy between adjacent transmitting and reception antenna disk.Arrange isolation chokes frontier district so that the frequency range of isolation is adjustable, this hereafter will to be specifically described.Such as, isolation chokes frontier district can adjust by regulating the height of its crestal line.
Isolation boundary region may be mounted at the outward flange on (or exceeding at least partly) chokes border.In some deformation, chokes frontier district can be suspended in the distal openings of shield region.Such as, chokes shield region can comprise more than 12 crestal lines.These crestal lines can have the inclination less than 0.35 inch.These crestal lines can arrange along with the flexibility of the opening of reflector.These crestal lines can be separated by raceway groove.The segmentation of crestal line (such as, the width of raceway groove and/or the degree of depth) can be constant can also be change.In some deformation, the height of crestal line is different.Such as, adjacent crestal line can have different height (from high to low, or high/low alternately, etc.), to " on " extend the plane of the opening of reflector.
Those above embodiment describes the different arrangements of these crestal lines and raceway groove.As a rule, chokes frontier district could be arranged to low Q structure, such that it is able to arrange as far as possible many crestal lines, without the restriction being subject to the ability of antenna connected.
As shown in figure 6 above, the arrangement of the crestal line of chokes frontier district can so that these crestal lines not in one plane, adjacent crestal line can be by curved surface (such as, sinusoidal) or cascade arrangement.Such as, the perspective view shown in Fig. 6, the crestal line extended to side along surface the upper surface of the chokes frontier district formed is uneven.The apparent height of adjacent crestal line also differs, and some crestal lines stretch out more along the first type surface (" top " on chokes border) on chokes border.Become apparent from from the side view shown in Fig. 7.The crestal line of the part through chokes center in figure, it is shown that these crestal lines are with the situation of curved surface (such as, sinusoidal) formula arrangement.The apparent height of these crestal lines is different from.In some deformation, the space between crestal line, and/or the degree of depth can also differ (such as, between 9mm to 19mm).
As it has been described above, the surface of chokes frontier district and shield region can bend with antenna house.As it is shown in fig. 7, in the deformation of some chokes guard shields, chokes region can be arranged on the edge of shield region, and (prolong than sub-reflector and project farther) before the sub-reflector of each reflex system.In this embodiment, there is low frequency wave attribute chokes frontier district at high frequency salient point (carinate point).When antenna reflector (antenna) and other antennas are adjacent or near time, this can improve the isolation of antenna reflector (antenna).
In some deformation, isolation chokes frontier district and/or chokes region can include the part absorbing (such as, microwave absorption) material as its structure.This absorbing material can absorb relative to using device energy within the scope of certain frequency.Such as, when chokes border is arranged between these two antenna disks, absorption band or uptake zone, such as microwave absorption band or microwave absorption district can extend between two antenna disks.A kind of microwave material includes the polymeric material being filled with magnetic particle；These microgranules can have high magnetic susceptibility (magnetic loss characteristic) and high permittivity (dielectric loss characteristics) simultaneously.Absorbing material can be that solid (such as, magnetic) absorbs and/or foam absorbing.Such as, foam absorbing, it is also possible to be Open cell shape, or be by the lossy material of some frequency (such as, carbon coating) dipping is made.Absorbing material can in chokes guard shield (such as, the long axis along chokes guard shield extends, and is arranged in the middle of two reflection disks).Absorbing material can have any suitable thickness, width and length, such as at about thickness between 0.5mm to 5cm and/or width, etc..Absorbing material can have shape (for example, it is possible to including salient point, crestal line etc.) and/or form the crestal line of one or more chokes frontier district.
Application also describes isolation boundary (isolation chokes border) region, it is possible to the adjustment of automatic or manual is to adapt to isolation frequency.Such as, isolation chokes guard shield can pass through the height adjusting the crestal line extended between reflector to regulate.According to desired transmission/reception frequency bandwidth, it is possible to regulating crestal line height is specific height or altitude range/distribution.As a rule, according to bandwidth, the height of crestal line can be the mark (such as, 1/4) of wavelength, and could be arranged to or centered by the mid frequency of bandwidth.Such as, the operating frequency of bandwidth is 5470-5950MHz, and mid frequency is 5710MHz, then the height (or centre-height) of the crestal line in chokes region is about 13.25mm.Similar, the operating frequency using bandwidth is 5725-6200MHz, and mid frequency is 5962.5MHz, then the height (or centre-height) of the crestal line in chokes region is about 12.6mm.Therefore, if using adjustable chokes region, then the desired bandwidth of work changes, the height of these crestal lines can regulate to 12.6mm from about 13.25mm.
The height of these crestal lines can be regulated by mechanical adjustment crestal line so that the base on they extended or retracted chokes borders.In some deformation, these crestal lines can machinery (and/or electric power) extended or retracted pedestal to regulate to different height.These highly can manual adjustments, i.e. use handle or other manipulation devices, and including the manipulation device of preset height, this preset height corresponds to the desired bandwidth of work.All these device can also be automatically adjusted, i.e. controls wireless circuit and can also control and/or regulate the height of isolation barrier crestal line；If the bandwidth of operation of conversion equipment is from a bandwidth (such as, 5470-5950MHz) to another bandwidth (such as, 5725-6200MHz), then it can tune automatically, or regulate the height of the crestal line in chokes region.Such as, the height of crestal line can about 4mm and about between 20mm regulate (such as, 8mm to 20mm, 10mm to 18mm, etc.).In some deformation, the spacing between crestal line is adjustable.
As a rule, the substantial amounts of crestal line isolating chokes frontier district can extend across the external margin of guard shield district and/or parabola.Chokes border (" chokes ") can include any an appropriate number of crestal line.Such as, chokes region can include at least 10 crestal lines or the crestal line of other quantity any of the above described.As it has been described above, chokes frontier district can include a plurality of crestal line.In some deformation, first subset of the crestal line in isolation chokes region, can bend along with the external margin of the first protective cover end (in the principal plane on isolation chokes border), the second subset of the crestal line in isolation chokes region, it is possible to along with the external margin of the second protective cover end bends.
, from the cross section in chokes region, can there be different section profiles all of isolation chokes frontier district described herein, but be typically all relative to long axis plane symmetry.Optionally, in some deformation, there is asymmetric rib height profile in chokes region, therefore symmetrical it is not necessary to.
Wireless device for sending wideband wireless signal may include that parabola；Radio-circuit, is the broadband RF signal between 4GHz to 8GHz for sending and receive frequency from parabola；Chokes guard shield, is connected to or is attached on reflector, and this reflector includes isolation chokes frontier district and shield region.Isolation chokes frontier district can include substantial amounts of crestal line, and these crestal lines are perpendicular to the central axis of chokes guard shield and extend.Isolation chokes frontier district can realize the parabola more than 10dB and isolate.
