Fig. 2 is that antenna embodiment illustrated in fig. 1 back side feed is arranged schematic diagram.
Detailed description of the invention
Understand technology contents of the present invention for convenience of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.
The method for designing of 4G antenna of the present invention is to be switched to corresponding antenna based on complete antenna by switching over when the different operating frequency band, so must increase the on-off circuit of antenna on circuit, increases different contact points simultaneously on antenna.
Described method is specific as follows: the whole frequency range that 4G antenna need be covered is divided into continuously several but frequency range independently, according to the designing antenna cabling respectively of the frequency range after cutting apart; Corresponding each frequency range design one feedback place again, and on-off circuit is set. Feedback place is connected to antenna cabling by on-off circuit, by just realizing the control of on-off circuit when the different frequency range by the antenna of different feedback place connection different operating frequencies, realizes comprehensive covering of each frequency range of 4G antenna like this. When design, the antenna cabling of each frequency range designs together as far as possible. Like this, some antenna cabling contacts with the selection in feedback place according to distributing point, can integrate the multiplexing different antenna working frequency range that covers, and need not each frequency range use separately an antenna cabling, saves space and cost.
As shown in Figure 1, 2, be the example structure schematic diagram of the 4G antenna that obtains according to the method for the invention. In the present embodiment, the frequency band that 4G antenna need be covered is divided into 689-824MHz frequency range, 824-960MHz frequency range, 1710-2170MHz frequency range and 2.3-2.69Ghz frequency range. Design respectively antenna cabling for said frequencies section. As figure, corresponding 689-824MHz frequency range be the first feedback place 10 and stepped antenna cabling C. The second feedback place 8 and convex antenna cabling B of corresponding 824-960MHz frequency range and 1710-2170MHz frequency range, convex antenna cabling lower-left end opening. The U-shaped antenna cabling A of corresponding 2.3-2.69Ghz frequency range. Wherein, one of them termination of stepped antenna cabling C, convex antenna cabling B and U-shaped antenna cabling A is respectively as the first distributing point 11, the second distributing point 9 and the 3rd distributing point 7. Stepped antenna cabling C, conveniently switches by termination and the first feedback place 10, the second feedback place 8 spacing parallel arranging settings successively of termination 9, U-shaped antenna cabling A by termination 11, convex antenna cabling B.
When concrete application, circuit between from power amplifier to antenna connector is continued to use prior art, each distributing point all directly connects power amplifier, only need before antenna feed place and antenna connector, increase described on-off circuit 6, while needing to use any road antenna cabling, Jiang Gai road antenna cabling and corresponding feedback place connection.
In the present embodiment, the contact 1,3,5 of on-off circuit 6 shown in Fig. 2 all connects power amplifier incoming radio frequency signal, and 2,4 connect earth signal; And the contact 1,3,5 of on-off circuit 6 respective antenna cabling face distributing point 7,9,11 respectively; 2, the 4 respective antenna feedback places 8,10, contact of on-off circuit 6. In the time that mobile terminal device need to be operated in 689-824MHz frequency band, on-off circuit 6 is by extremely corresponding gear of switching over, use the combination 4,5 of feedback point, be communicated with 10(Kui place, connection of antenna contact), 11(distributing point), use antenna cabling C, meet the requirement of mobile terminal device work 698-824Mhz; In the time that mobile terminal device need to be operated in 824-960MHz and 1710-2170MHz frequency band, on-off circuit 6 by switching over to B1, use feedback ground combination 2,3, be communicated with 8(Kui place, connection of antenna contact), 9(distributing point), use antenna cabling B, meet the requirement of mobile terminal device work 824-960MHz and 1710-2170MHz; In the time that mobile terminal device need to be operated in 2.3-2.69Ghz frequency band, on-off circuit 6 to C1, uses feedback ground combination 1 by switching over, is communicated with connection of antenna contact 7(distributing point), use circuit A, meet the requirement of mobile terminal device work 2.3-2.69Ghz.
The present invention is switched by on-off circuit the expansion that different Circuit Matchings completes the beamwidth of antenna and is had certain similitude from current, but the switching that focuses on the feedback different by switching over and combined different antennae of the present invention. Cover in the antenna adjustment of different frequency range in different antennae, can complete with match circuit too the design of antenna.
Above-described embodiment is only preferably implementation of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention. It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these apparent replacement forms all belong to protection scope of the present invention.
