Abstract

The application discloses a wide-bandwidth multi-frequency microstrip antenna comprising a dielectric layer, a radiation paster formed on one surface of the dielectric layer, and a grounding part formed on the other surface of the dielectric layer. The radiation paster is in a rectangular shape; and two arc gaps are formed symmetrically on the paster. According to the invention, two resonance frequencies are generated by the two arc gaps. Compared with the rectangular patch antenna, the provided antenna has the effectively improved frequency band width.

Description

A kind of multifrequency microstrip antenna of high bandwidth

Technical field

The application belongs to wireless communication technology field, particularly relates to the multifrequency microstrip antenna of a kind of high bandwidth.

Background technology

Although printed circuit board (PCB), dipole antenna are all good function antennas, but are intended to relatively Narrow bandwidth operation.Narrow bandwidth of operation limits printed circuit board (PCB), dipole antenna at such as IEEE The application on required equipment is operated on the big broadband of 802.11a frequency band.

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

Summary of the invention

It is an object of the invention to provide the multifrequency microstrip antenna of a kind of high bandwidth, to overcome in prior art Deficiency.

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

The embodiment of the present application discloses the multifrequency microstrip antenna of a kind of high bandwidth, including dielectric layer, is formed at Radiation patch on one surface of described dielectric layer and being formed on another surface of described dielectric layer Grounding parts, described radiation patch is rectangular, and on it, symmetry offers the gap of two arcs.

Preferably, in the multifrequency microstrip antenna of above-mentioned high bandwidth, the song in the gap of said two arc Face is relative.

Preferably, in the multifrequency microstrip antenna of above-mentioned high bandwidth, the two of the gap of described each arc End extends from two drift angles of described radiation patch respectively.

Preferably, in the multifrequency microstrip antenna of above-mentioned high bandwidth, the material of described dielectric layer is poly-four Fluorothene.

Compared with prior art, it is an advantage of the current invention that: the present invention is permissible by the gap of two arcs Produce two resonant frequencies, compared with the paster antenna of rectangle, can being effectively improved frequently of present configuration Bandwidth.

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, the multifrequency microstrip antenna of high bandwidth, including dielectric layer 1, it is formed at dielectric layer one Radiation patch 2 on surface and be formed at the grounding parts on another surface of dielectric layer, radiation patch 2 Rectangular, on it, symmetry offers the gap 3 of two arcs.

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

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

Further, the material of dielectric layer is politef.

The present invention can produce two resonant frequencies, with the paster antenna of rectangle by the gap of two arcs Compare, present configuration can be effectively improved bandwidth.
