Abstract

The application discloses microstrip paster antenna, including the dielectric plate, formed at the radiation paster on dielectric plate no. 1 surface, formed at another surperficial ground plate of dielectric plate and connection are in coaxial probe between radiation paster and the ground plate, the concave first gap of the rectangle that is formed with 3 parallels of establishing in one side edge of ground plate, the concave rectangle second gap that is formed with 2 parallels of establishing in opposite side edge that the ground plate is relative, first gap and second gap length set up the utility model discloses an at on paster fluting simultaneously of ground plate and radiation, can realize RCS's the reduction by a wide margin of singly standing to the plane wave of incident, and not have in whole frequency channel and encouraged new peak value, the utility model discloses the contradiction between the requirement of radiance and low RCS has been solved betterly.

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, because its size is little, lightweight and easy and that carrier is conformal feature, various optimal in structure is widely applied.Along with high-tech war is to the demand of target stealth capabilities, the RCS of antenna contributes larger problem to become increasingly conspicuous to the overall RCS of optimal in structure.Therefore, the RCS of reduction micro-strip paster antenna becomes a study hotspot in recent years.But under the prerequisite ensureing antenna radiation performance, existingly reduce scheme mostly only to the Reduce shrinkage effect that some narrow frequency ranges have had; Though what have can reduce RCS in wide-band, sacrifice the amplitude of reducing, and often encourage new peak value.

Utility model content

The purpose of this utility model is to provide a kind of micro-strip paster antenna, to overcome deficiency of the prior art.

For achieving the above object, the utility model provides following technical scheme:

The embodiment of the present application discloses a kind of micro-strip paster antenna, comprise dielectric-slab, be formed at the radiation patch on described dielectric-slab one surface, the ground plate being formed at described another surface of dielectric-slab and the coaxial probe be connected between described radiation patch and ground plate, one lateral edges of described ground plate is recessed is formed with 3 parallel rectangle first gaps, the opposite side edge that described ground plate is relative is recessed is formed with 2 parallel rectangle second gaps, and described first gap and the second gap length are arranged.

Preferably, in above-mentioned micro-strip paster antenna, described coaxial probe is between described 2 the second gaps.

Preferably, in above-mentioned micro-strip paster antenna, described radiation patch offers the gap of 2 circles arranged side by side, 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 gap of a rectangle, 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 polytetrafluoroethylene.

Compared with prior art, the utility model has the advantage of: the utility model by slotting simultaneously on ground plate and radiation patch, the significantly reduction of mono-static RCS can be realized to the plane wave of incidence, and do not have to have encouraged new peak value in whole frequency range, the utility model solve preferably radiance and low RCS require between contradiction.

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Figure 1 shows that the structural representation of the radiation patch of micro-strip paster antenna in the utility model specific embodiment;

Figure 2 shows that the structural representation of the ground plate of micro-strip paster antenna in the utility model specific embodiment.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be described in detail the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.

Shown in ginseng Fig. 1 and Fig. 2, micro-strip paster antenna, comprise dielectric-slab, be formed at the radiation patch 1 on described dielectric-slab one surface, the ground plate 2 being formed at described another surface of dielectric-slab and the coaxial probe be connected between described radiation patch and ground plate, one lateral edges of described ground plate 2 is recessed is formed with 3 parallel rectangle first gaps 21, the opposite side edge that described ground plate is relative is recessed is formed with 2 parallel rectangle second gaps 22, and 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 the gap 11 of 2 circles arranged side by side, the gap of this circle is positioned at the top in described first gap.

Further, described radiation patch offers 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 polytetrafluoroethylene.

The utility model by slotting simultaneously on ground plate and radiation patch, the significantly reduction of mono-static RCS can be realized to the plane wave of incidence, and do not have to have encouraged new peak value in whole frequency range, the utility model solve preferably radiance and low RCS require between contradiction.

It should be noted that, in this article, the such as relational terms of first and second grades and so on is only used for an entity or operation to separate with another entity or operating space, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.

The above is only the embodiment of the application; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection range of the application.
