Description

A kind of Two--Layer Microstrip Antenna

Technical field

The application belongs to wireless communication technology field, particularly relates to a kind of Two--Layer Microstrip Antenna.

Background technology

Although printed circuit board (PCB), dipole antenna are all good function antennas, tend to relatively narrow bandwidth operation.Narrow bandwidth of operation limits printed circuit board (PCB), dipole antenna on the large broadband of such as IEEE802.11a frequency band, operates application on required equipment.

In view of this, the flat plane antenna that a kind of high bandwidth is provided is necessary.

Utility model content

The purpose of this utility model is to provide a kind of Two--Layer Microstrip 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 Two--Layer Microstrip Antenna, comprise first medium layer setting up and down and second dielectric layer, bracing or strutting arrangement is provided with between described first medium layer and second dielectric layer, described first medium layer and second dielectric layer interval are arranged, the lower surface of described first medium layer is provided with the first radiation patch, the upper surface of described second dielectric layer is provided with the second radiation patch, grounding parts is provided with below described second dielectric layer, described first radiation patch comprises the main part of rectangle, two sides of this main part set to the concave respectively and are formed with the recessed portion of arc.

Preferably, in above-mentioned Two--Layer Microstrip Antenna, described second radiation patch is rectangular, and on it, symmetry offers the gap of two arcs.

Preferably, in above-mentioned Two--Layer Microstrip Antenna, the curved surface in the gap of described two arcs is relative.

Preferably, in above-mentioned Two--Layer Microstrip Antenna, the two ends in the gap of described each arc extend from two drift angles of described radiation patch respectively.

Preferably, in above-mentioned Two--Layer Microstrip Antenna, the material of described first medium layer and second dielectric layer is polytetrafluoroethylene.

Compared with prior art, the utility model has the advantage of: in the utility model, can be improved the bandwidth of dual-layer atenna by arc shaped slits further, gain simultaneously also can not significantly reduce.

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 Two--Layer Microstrip Antenna in the utility model specific embodiment;

Figure 2 shows that the structural representation of the first radiation patch in the utility model specific embodiment;

Figure 3 shows that the structural representation of the second radiation patch 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 to Fig. 3, Two--Layer Microstrip Antenna comprises first medium layer 1 setting up and down and second dielectric layer 2, bracing or strutting arrangement 3 is provided with between first medium layer 1 and second dielectric layer 2, first medium layer 1 and second dielectric layer 2 interval are arranged, the lower surface of first medium layer 1 is provided with the first radiation patch 11, the upper surface of second dielectric layer 2 is provided with the second radiation patch 21, grounding parts 22 is provided with below second dielectric layer 2, first radiation patch 11 comprises the main part 111 of rectangle, and two sides of this main part set to the concave respectively and are formed with the recessed portion 112 of arc.

Further, the second radiation patch 21 is rectangular, and on it, symmetry offers the gap 211 of two arcs.

Further, the curved surface in the gap of two arcs is relative.

Further, two drift angles of the two ends difference autoradiolysis paster in the gap of each arc extend.

Further, the material of first medium layer and second dielectric layer is polytetrafluoroethylene.

In the utility model, can be improved the bandwidth of dual-layer atenna by arc shaped slits further, gain simultaneously also can not significantly reduce.

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.
