Abstract
This utility model is related to a kind of micro-strip paster antenna for reducing coupling, and microband paste structure realizes the reduction of antenna return loss and coupling, and the reduction of two paster distances realizes compact space structure.The symmetrical paster antenna in both sides adopts feed microstrip line technology, it is ensured that antenna has good impedance matching and bandwidth.50 ohm microstrips are using the embedded paster of embedded feeding classification, it is ensured that effective transmission and the matching of antenna of signal.Two grooves are loaded with the middle of two radiation patch, make that electric current complications detour and active path is elongated, patch resonant frequency is reduced, and has intercepted the coupling between paster.This utility model realizes the reduction of return loss and coupling well, increases isolation, while reducing the size of paster antenna accordingly.
Description
Technical field
This utility model is a micro-strip paster antenna for reducing coupling.The antenna is used for mobile communication and the Internet skill
Art.
Background technology
In recent years, with the continuous development of Internet technology and mobile communication technology, many new hot spot technologies meet the tendency of and
It is raw, such as REID, Internet of Things, WiMAX LAN, Metropolitan Area Network (MAN), WiMAX LAN etc., this just in the urgent need to
The efficiency of transmission of raising information, wherein the efficiency of transmission for improving antenna is its core.
In order to improve the efficiency of transmission of antenna, it is necessary to improve the isolation of antenna to reduce various interference.In prior art
It is middle to there are many methods for improving isolation, such as increase the space length of two antennas, can so reduce the surface row of antenna
Ripple, but the size of antenna can be increased；Electro-magnetic bandgap (EBG) structure is added, the surface wave of microstrip substrate can be suppressed, reduce day
Mutual coupling between linear array column unit, so as to improve the isolation of antenna, but the complicated design of EBG structures, also occupies than larger
Area.
The content of the invention
Problem to be solved by this invention is to reduce the mutual coupling between antenna patch, increases the isolation of antenna.
In order to solve this problem, this utility model is realized by following technical scheme：
A kind of micro-strip paster antenna for reducing coupling, including medium substrate, earth plate, radiant body and loading groove, the spoke
Beam includes rectangular patch and 50 ohm of microstrip line, in 50 ohm of the embedded rectangular patch of microstrip line；Loading groove is arranged on and connects
On floor, and paster is not at same aspect, when optimizing the width of groove, does not interfere with the shape of paster, and will not increase day
The area of line.
Preferably, by increasing by two loading grooves come the reduction for realizing return loss and couple, the increase of isolation.
Preferably, the radiant body is symmetrical structure.
Preferably, the radiant body adopts feed microstrip line mode.
The addition of technical solutions of the utility model bracket groove changes the CHARGE DISTRIBUTION on conducting medium layer, so as to change day
Electric Field Distribution on beta radiation unit.The change of Electric Field Distribution can reduce the degree of coupling between radiating element, increase aerial radiation
The isolation of unit, reduces standing-wave ratio.Therefore, this utility model can effectively improve the isolation between antenna radiation unit,
And too big area will not be occupied.

Specific embodiment
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect become more apparent, with
Under in conjunction with the accompanying drawings and embodiments, this utility model is further described in detail.It should be understood that described herein concrete
Example only to explain this utility model, is not used to limit this utility model.
The radiating element of paster antenna is two rectangular patches 1, symmetrical, and at a distance of the distance of half wavelength.50
Ohm microstrip 2 is respectively embedded into two pasters 1 using the feedback of embedded micro-strip side, and paster and microstrip line are integrated into an entirety.My god
Line adopts feed microstrip line, meets the requirement of miniaturization.
Separated by gap between paster, gap is made up of the groove of two same shapes, groove is shaped like in aerial ladder, two
Groove is mutually twisted, and is conducive to reducing the size of antenna.
Relatively Fig. 2 and Fig. 3, it can be seen that plus groove and be not added with groove, the numerical value of S12 is widely different, and when being not added with groove, S12 values are-
9dB, plus during groove, S12 values are -20dB, it can be seen that the isolation numerical value of antenna increases 11dB, hence it is evident that inhibit surface wave,
Reduce coupling.So the utility model proposes scheme be effective.
