Preferably, described substrate 7 adopts gum and described antenna holder 21 to be fixedly connected.
Preferably, described isolation spacing A is 8mm.Isolation spacing A finally obtains according to the parameter of two antennas of debugging, and isolation spacing A can change along with the variation of antenna parameter, is also to change along with the size of POS machine inner space.
Preferably, described radiation fin 9 is Copper Foil.Because aerial radiation needs certain area, if the too little performance index of swept area just do not reach, therefore needing increases a radiation fin 9, in order to improve its performance.And, radiation fin 9 of the present invention is vertical with antenna body fixing, radiation fin 9 is attached on external PCB mainboard simultaneously, and be connected with the earth terminal of mainboard, so just can make antenna body also vertical fixing with mainboard, can either guarantee the receptivity of antenna, because increase radiation fin 9, not increase again the thickness of equipment.
The design of the POS machine that includes the multimode common antenna provided by the invention is specific as follows:
Because the POS machine intimate is provided with printer, camera, scan first-class device, self radiation meeting of these devices impacts the performance of antenna, the larger metal device away from these that therefore just must try one's best when installing, also consider that in addition the intense radiation of antenna can disturb the signal of responsive module on plate, so antenna just need to be away from responsive modules such as magnetic card head, SIM card seats, consider again the handheld device that existing a lot of POS machines are the PDA formula, the custom of shaking hands of staff is generally the two ends of holding with equipment, the top of therefore antenna being put to machine, just can reduce the impact of staff, consider above-mentioned factor, the installation of multimode common antenna provided by the invention just need to be arranged on the side of equipment, the angle of its reception simultaneously, preferably perpendicular to equipment, therefore it is fixed in the present invention adopts radiation fin 9 on the PCB mainboard of POS machine, and be arranged at the edge of the close equipment side of mainboard, and the substrate 7 of antenna body of the present invention, just perpendicular with this radiation fin 9, and the side near equipment, when equipment keeps flat, the range of receiving of antenna just is the top of equipment, so just can eliminate staff to the shield effectiveness of aerial signal.And, in this scheme design, because the inner space of PDA POS own is very compact, the space that can use seldom, therefore on Antenna Design, allow the working frequency range of antenna be confined to, in zone separately, just can accomplish higher isolation as far as possible, drop to interfering with each other between antenna minimum.As shown in fig. 1, in design, be the isolation spacing A of 7mm-13mm between the radiant body of two antennas, two antennas adopt same reference horizontal plane of manufacturing simultaneously, preferably, isolation spacing A is 8mm, and 8 of solder joints are for radiation fin 9 and pcb board, and five frequency antennas 3 share radiation fin 9 these reference horizontal plane of manufacturing with 2.4G antenna 6.Can eliminate preferably the impact between antenna so in design.
Refer to Fig. 4 and Fig. 5, this standing-wave ratio that is five frequency antennas in multimode common antenna provided by the invention, described standing-wave ratio full name is voltage standing wave ratio, i.e. VSWR(Voltage Standing Wave Ratio).
The principle of standing-wave ratio is: the place identical with the reflected wave phase place at incident wave, and voltage amplitude adds up to maximum voltage amplitude Vmax, forms antinode; Local voltage amplitude at incident wave and reflected wave single spin-echo is kept to minimum voltage amplitude Vmin mutually, forms node.The amplitude of other each point is between antinode and node.This composite wave is called moving standing wave.Standing-wave ratio is the sound pressure amplitude Vmax at standing wave antinode place and the ratio of the acoustic pressure Vmin amplitude at node place.In radio communication, the impedance mismatch of the impedance mismatch of antenna and feeder line or antenna and transmitter, high-frequency energy will produce reflection and turn back, and disturbs and converge the generation standing wave with the part of advancing.In order to characterize and measure the stationary wave characteristic in antenna system, the situation of forward wave and reflected wave in antenna namely, people have set up " standing-wave ratio " this concept,
SWR=R/r=(1+K)/(1-K)，
Reflection coefficient K=(R-r)/(R+r) (K shows single spin-echo while being negative value),
In above formula, R and r are respectively output impedance and input impedance.When two impedance value are the same, reach coupling fully, reflection coefficient K equals 0, and standing-wave ratio is 1.This is a kind of desirable situation, in fact always have reflection, so standing-wave ratio always is greater than 1.
In Fig. 3, included frequency range is 824M-960M and 1710M-2170M, and CDMA800M, GSM900M, GSM1800M, PCS1900M and IMT-2000 also are listed in wherein.The 824M-960M standing-wave ratio is between 2-2.5, and its standing-wave ratio of 1710M-2170M is between 1-1.5.The standing-wave ratio that Fig. 4 is 2.4G antenna provided by the invention.2.4G the operating frequency of antenna is 2400MHz-2500MHz, its standing-wave ratio is between 1-1.5.
Above-mentioned data show, five frequently the standing-wave ratio of antennas and 2.4G antenna be less than normal, approach 1, this explanation, its output impedance and input impedance are comparison match, and the interference between two antennas is very little.
In sum, multimode common antenna provided by the invention utilizes the isolation spacing of being 7mm-13mm between the radiant body of two antennas, and two antennas adopt same reference horizontal plane of manufacturing, realized compatible multiple wireless communication mode and solved the signal interference between different communication modes.In addition, the vertical fixing structure that it utilizes radiation fin 9 and antenna, make the present invention in less volume range, not need practical other parasitic couplings monotechnicss to compensate the gain of antenna, improved the practicality of product.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure transformation that utilizes specification of the present invention and accompanying drawing content to do, or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
