Abstract

The invention discloses a microstrip patch antenna. The microstrip patch antenna comprises a dielectric plate, a radiation patch, a grounding plate and a coaxial probe, wherein the radiation patch is formed on one surface of the dielectric plate, the grounding plate is formed on the other surface of the dielectric plate, the coaxial probe is connected between the radiation patch and the grounding plate, three rectangular first gaps in parallel are sunken and formed in an edge of one side of the grounding plate, two rectangular second gaps in parallel are sunken and formed in an edge of the other opposite side of the grounding plate, and the first gaps and the second gaps are arranged at intervals. By simultaneously forming grooves in the grounding plate and the radiation patch, substantial reduction of single-station RCS on an incident planar wave can be achieved, and moreover, a new peak is not simulated in the whole frequency band. By the microstrip patch antenna, the conflict between the radiation performance and low RCS requirement is solved very well.

Description

A kind of micro-strip paster antenna

Technical field

The application belongs to wireless communication technology field, particularly relates to a kind of micro-strip paster antenna.

Background technology

Micro-strip paster antenna is because its size is little, lightweight and the feature the most conformal with carrier, at various works Draw and be widely applied on platform.Along with the high-tech war demand to target stealth capabilities, antenna Optimal in structure entirety RCS is contributed bigger problem to become increasingly conspicuous by RCS.Therefore, microband paste sky is reduced The RCS of line becomes a study hotspot in recent years.But it is on the premise of ensureing antenna radiation performance, existing Have reduces the Reduce shrinkage effect that some narrow frequency ranges have the most only been had by scheme；Though have can be in wide-band Reduce RCS, but sacrifice the amplitude of reducing, and often encouraged new peak value.

Summary of the invention

It is an object of the invention to provide a kind of micro-strip paster antenna, to overcome deficiency of the prior art.

For achieving the above object, the present invention provides following technical scheme:

The open a kind of micro-strip paster antenna of the embodiment of the present application, including dielectric-slab, is formed at described dielectric-slab The radiation patch on one surface, it is formed at the earth plate on described another surface of dielectric-slab and is connected to described Coaxial probe between radiation patch and earth plate, a lateral edges of described earth plate is recessed is formed with 3 Parallel rectangle the first gap, opposite side edge that described earth plate is relative is recessed be formed 2 parallel Rectangle the second gap, described first gap and the second gap length are arranged.

Preferably, in above-mentioned micro-strip paster antenna, described coaxial probe is positioned at described 2 second seams Between gap.

Preferably, in above-mentioned micro-strip paster antenna, described radiation patch offers 2 arranged side by side Circular gap, the gap of this circle is positioned at the top in described first gap.

Preferably, in above-mentioned micro-strip paster antenna, described radiation patch offers the seam of a rectangle Gap, the gap of this rectangle is positioned at the top in described second gap.

Preferably, in above-mentioned micro-strip paster antenna, the material of described dielectric-slab is politef.

Compared with prior art, it is an advantage of the current invention that: the present invention is by earth plate and radiation patch Upper slot simultaneously, incident plane wave can be realized the significantly reduction of mono-static RCS, and at whole frequency Not encouraged new peak value in section, the present invention preferably solves between radiance and low RCS requirement Contradiction.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out Detailed description, it is clear that described embodiment is only a part of embodiment of the present invention rather than complete The embodiment in portion.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation Property work on the premise of the every other embodiment that obtained, broadly fall into the scope of protection of the invention.

Shown in ginseng Fig. 1 and Fig. 2, micro-strip paster antenna, including dielectric-slab, it is formed at described dielectric-slab one The radiation patch 1 on surface, it is formed at the earth plate 2 on described another surface of dielectric-slab and is connected to described Coaxial probe between radiation patch and earth plate, a lateral edges of described earth plate 2 is recessed is formed with 3 Individual parallel rectangle the first gap 21, opposite side edge that described earth plate is relative is recessed to be formed with 2 and puts down Rectangle second gap 22 of row, described first gap and the second gap length are arranged.

Further, described coaxial probe is between described 2 the second gaps.

Further, described radiation patch 1 offers 2 circular gaps 11 arranged side by side, this circle Gap be positioned at the top in described first gap.

Further, described radiation patch offering the gap 12 of a rectangle, the gap of this rectangle is positioned at The top in described second gap.

Further, the material of described dielectric-slab is politef.

Incident plane wave, by slotting on earth plate and radiation patch simultaneously, can be realized by the present invention The significantly reduction of mono-static RCS, and do not have to have encouraged new peak value in whole frequency range, the present invention is preferable Solve radiance and low RCS require between contradiction.
