Please refer to Fig. 6, its position that shows the secondary speculum 14 of frequency division of the present utility model and main electric wave transmitting-receiving mechanism 16 and reflection electric wave transmitting-receiving mechanism 18 concerns profile.
If the angle of the secondary speculum 14 of this frequency division of an incident wave incident is θ 1, Fig. 3 a shows the configuration mode of the assembly of this incident wave and secondary speculum 14 minute surfaces of frequency division, Fig. 3 b then is feedback loss measured under the different frequency, in this figure, the electromagnetic wave of six horizontal polarizations is tested, wherein these six electromagnetic waves are all with angle θ 1 incident perpendicular to the secondary speculum 14 of this frequency division, and namely θ 1 is 90 degree.When the orientation that bipolar grating structure is set, arrangement angle has different crossing angles, and these intersecting angles are respectively 15 °, 30 °, 45 °, 60 °, 75 ° and 90 °, please refer to the honeycomb structure figure of Fig. 3 a.As showing among Fig. 3 b, when incident angle θ 1 is 90 when spending, measured feedback loss under the different frequency.Suitable low of its feedback loss when wherein being presented at frequency 9GHz to 15GHz be not so most incident wave can have great consume from secondary speculum 14 reflections of this frequency division under this frequency band.Relative when the scope of frequency to 17GHz to 30GHz the suitable height of its feedback loss, so most incident wave will penetrate this frequency division pair speculum 14 and can not reflect under this frequency band.So the system that we can understand this case by last relation of plane is that 9GHz has good reflectivity with respect to the secondary speculum 14 of this frequency division during to 15GHz (low frequency) in frequency, so this signal can be reflected to this reflection electric wave transmitting-receiving mechanism 18, and is received by this reflection electric wave transmitting-receiving mechanism 18.The system of this case is that 17GHz has good penetrability with respect to the secondary speculum 14 of this frequency division during to 30GHz (high frequency) in frequency in addition, so this signal can penetrate the secondary speculum 14 of this frequency division, and is received by this main electric wave transmitting-receiving mechanism 16.In this figure the electromagnetic wave of six horizontal polarizations is tested, its arrangement angle with respect to honeycomb structure has different crossing angles, and these intersecting angles are respectively 15 °, 30 °, 45 °, 60 °, 75 ° and 90 °.Feedback by Fig. 3 b is lost as can be seen, is 90 degree at incident angle, and under the different intersecting angle, the not too big change of its effect.
Please refer to Fig. 4, wherein show incident electromagnetic wave with the secondary speculum 14 of this frequency division of the direction incident of horizontal polarization, wherein incidence angle θ 1 is respectively 15 °, 30 °, 45 °, 60 °, 75 ° and 90 ° (please refer to right-hand structure configuration map of figure).Wherein show with respect to its feedback loss value of different incidence angles to diminish, especially when high frequency, will be unfavorable for the characteristic that penetrates.So we need to consider this characteristic at the secondary speculum 14 of this frequency division of design.Configuration and arrangement for honeycomb structure must give suitable design, and make that when different angles the curve of its feedback loss can trend towards the feedback loss curve of 90 ° of desirable incidence angles.
Please refer to Fig. 5, wherein show the electromagnetic wave of incident with the secondary speculum 14 of this frequency division of direction incident of perpendicular polarization, wherein incidence angle θ 1 is respectively 15 °, 30 °, 45 °, 60 °, 75 ° and 90 °.Wherein showing with respect to its feedback loss value of different incidence angles to diminish, is to be unfavorable for the characteristic that reflects when the low frequency by it.So we need to consider this characteristic at the secondary speculum 14 of this frequency division of design.Configuration and arrangement for honeycomb structure must give suitable design, and make that when different angles the curve of its feedback loss can trend towards the feedback loss curve of 90 ° of desirable incidence angles.
Based on this test result, when honeycomb structure is set, should be in conjunction with precalculated incident wave angle, the orientation of the bipolar grating structure in each subregion is set, generally can be set to the interval different crossing angle of 0 to 90 degree, make the incident wave of any angle that the continuing surface of spending near 90 be arranged, namely incidence angle drops to the feedback loss minimum all near 90 degree.The honeycomb structure angular interval can be set to 10-15 degree, because 10-15 angular interval of spending influence little to reflection results.
As showing among Fig. 7, when a plurality of satellite signals signal transmission paths are respectively L1, L2 and L3, receiving system in this case wherein configuration mode of the secondary speculum 14 of this parabolic reflector 12 and this frequency division is same as person described in the above-mentioned figure six, use a plurality of electric waves to receive and dispatch mechanism only in this example, receive the signal from different satellites respectively.In the application of reality, the electric wave frequency range that each satellite sends has a certain distance, so if when the same electric wave transmitting-receiving mechanism that uses receives these signals simultaneously, in the manufacturing of the relevant RF circuit of back level, can have problems.So in this case, use different electric wave transmitting-receiving mechanism receptions from the signal of different satellites, to solve the above problems.
Concrete scheme is, comprises a plurality of main electric waves transmitting-receiving mechanism (16), wherein has at least the signal acceptance point of its front end of main electric wave transmitting-receiving mechanism (16) to approach with this prime focus, and each main electric wave is received and dispatched mechanism (16) and received electric wave from corresponding satellite respectively.A plurality of reflection electric waves are received and dispatched mechanism (18), wherein have at least signal acceptance point and this reflection focus (30b) of its front end of reflection electric wave transmitting-receiving mechanism (18) to approach, and each electric wave transmitting-receiving mechanism (18) that videos receives the electric wave from corresponding satellite respectively.
The advantage of this case is the selection through above-mentioned low frequency frequency range and high-frequency band, can be so that these two frequency ranges all be extreme broadband, and general all greater than 10% even can reach 50% frequency range, especially high band is than low-frequency range broadband more.So for follow-on satellite television (DBS), it requires low-frequency range must be satisfied with 10.7GHz to the following biography frequency range of 12.75GHz, the uploading of following biography, 24GHz and 30GHz (up-link) of the uploading of 17GHz, 18～20GHz then arranged at high band, is that 17～30GHz almost is altogether〉50% frequency range requirement.And the design of this case has reached above-mentioned frequency range requirement.Can make the design of traditional frequency division and speculum that a new idea and breakthrough are arranged.The honeycomb structure for the secondary speculum of frequency division is distinguished into several zones in this case in addition, the arrangement of honeycomb structure is separately arranged in each zone, honeycomb structure in each zone is evenly distributed and periodically arranges, and its honeycomb structure difference of zones of different, wherein the configuration of honeycomb structure mainly is that angle according to incident wave adjusts.This configuration can be so that the secondary speculum in this case can receive the radio wave of going into from different angles, and splendid bass reflex rate and high frequency penetrance all can be arranged.
In sum, the design of consideration of the utility model hommization, quite realistic demand.Its concrete improvement has disappearance now, obviously has breakthrough progressive advantage compared to prior art, the enhancement that has effect really, and non-being easy to reached.This case disclosed or was exposed on domestic and the external document and market, met patent statute.
