Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.
As shown in Figure 1, a kind of multiple antennas vehicle plate, including LTE primary antenna 1, V2X antenna 2, GNSS antenna 4, SDARS
Antenna 3, LTE slave antenna 5, RKE antenna 6 and Wi-Fi antenna 7.
LTE primary antenna 1, is applied to multiband, and working frequency is 698-960MHz and 1710-2690MHz.The main day LTE
Line 1 is made of steel disc material, is arranged on pcb board, and performance and structure are all very stable.
V2X antenna 2 works in 5850-5925MHz frequency range.2 working frequency range of V2X antenna is higher, it is affected by environment compared with
Greatly, it is designed on pcb board side, performance can be improved.In view of good directionality and high-gain, V2X uses PCB antenna shape
Formula.This Antenna Design inspiration comes from dipole antenna.
GNSS antenna 4, working frequency range 1559-1607MHz are located at pcb board center, it is ensured that antenna has good
Axis compare performance.Due to consideration that the requirement to circular polarisation and axis ratio, GNSS antenna 4 uses ceramic antenna form, and high dielectric is normal
Number can effectively reduce antenna size, save space.
SDARS antenna 3, working frequency range 2320-2345MHz are arranged in 4 center of top of GNSS antenna, it is ensured that
Antenna has good axis than performance, and will not influence the transmitting of GNSS antenna 4 or receive signal.Due to consideration that circular polarisation
With the requirement of axis ratio, SDARS antenna 3 uses ceramic antenna form, and high dielectric constant can effectively reduce antenna size, saves
Space.
LTE slave antenna 5, working frequency are 698-960MHz and 1710-2690MHz, cover multiband.Due to LTE pair day
Line 5 is identical as 1 working frequency range of LTE primary antenna, so dexterously LTE slave antenna 5 and LTE primary antenna 1 are respectively set when design
In the diagonal position of pcb board, mutual influence is effectively reduced, while all smaller by the shadow of other antennas, it is ensured that
The high performance requirements of two antennas.
RKE antenna 6 is contacted with pcb board using the form that steel disc welds, saves antenna carrier, not only saved cost but also saved
Save space, while stable structure, are effective to ensure that antenna performance.For RKE antenna 6 since frequency range is relatively low, the antenna needed is empty
Between it is bigger, so being designed in the long side of PCB, being not only able to satisfy space requirement but also being able to satisfy performance requirement.
Wi-Fi antenna 7 is embedded on pcb board for the dual-band antenna applied to 2.4G+5G, adjacent with RKE antenna 6.
This Antenna Design saves cost and space on pcb board, and can guarantee that dual-band antenna has good performance.Wi-Fi antenna 7
Design is near RKE antenna 6, and mentality of designing is ingenious, and two operating frequency of antenna are distant, influences to drop to most each other
It is low.
As shown in Fig. 2 to Fig. 8, this layout designs of the utility model can guarantee that each antenna reaches optimal performance,
The antenna for being included can satisfy the functional requirement of most of car antennas in the market, meet the demand in different clients and market.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
It is subject to the protection scope in claims.
