Abstract

The invention discloses a fractal microstrip antenna. The fractal microstrip antenna comprises a PCB (Printed Circuit Board) substrate and a radiation patch, wherein the radiation patch is formed on a surface of the PCB substrate and comprises a first patch, a second patch, a third patch and a fourth patch, the first patch is in a rectangular shape, the second patch is connected with a tail end of the first patch and is in a semi-circular shape, and the third patch and the fourth patch are connected with two tail ends of the second patch and are in semi-circular shapes. The antenna has the characteristics of relatively long electric length in a relatively small physical range, ultra wide band, high gain and quasi omnidirectional performance, and can be applied to various different wireless communication environments.

Description

A kind of microstrip fractal patch antennas

Technical field

The application belongs to wireless communication technology field, particularly relates to a kind of microstrip fractal patch antennas.

Background technology

Along with the development of telecommunications, people are more and more higher to the requirement of communication equipment, and antenna is as logical The reception of letter equipment and transmitting terminal adapt with the development of communication equipment.

Microstrip antenna, because of advantages such as its size are little, important gently, low cost is easily fabricated, is more come by people The most concerns.But narrow bandwidth is one of microstrip antenna major defect.

Summary of the invention

It is an object of the invention to provide a kind of microstrip fractal patch antennas, to overcome deficiency of the prior art.

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

The embodiment of the present application discloses a kind of microstrip fractal patch antennas, including PCB substrate and be formed at institute Stating the radiation patch on PCB substrate surface, described radiation patch includes the first paster of rectangle, is connected to institute State second paster in semicircular arc of the first paster end and be connected to described two ends of second paster The 3rd paster in semicircular arc of end and the 4th paster.

Preferably, in above-mentioned microstrip fractal patch antennas, described first paster is connected to described second paster On protruding arcwall face.

Preferably, in above-mentioned microstrip fractal patch antennas, two ends of described second paster connect respectively On the arcwall face that described 3rd paster and the 4th paster are protruding.

Preferably, in above-mentioned microstrip fractal patch antennas, described second paster and the junction point of the 3rd paster Being positioned at the centre of described 3rd paster, the junction point of described second paster and the 4th paster is positioned at the described 4th The centre of paster.

Preferably, in above-mentioned microstrip fractal patch antennas, described 3rd paster and the 4th paster are symmetrical Both sides in described first paster.

Compared with prior art, it is an advantage of the current invention that: the antenna of the present invention is in less physical extent Inside there is bigger electrical length, there is ultra-wide band, high-gain, accurate isotropic feature, can apply to Various different wireless communications environments.

Accompanying drawing explanation

In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, below will be to reality Execute the required accompanying drawing used in example or description of the prior art to be briefly described, it should be apparent that below, Accompanying drawing in description is only some embodiments described in the application, for those of ordinary skill in the art From the point of view of, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 show the structural representation of microstrip fractal patch antennas in the specific embodiment of the invention.

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, microstrip fractal patch antennas, including PCB substrate 1 and be formed at PCB substrate table The radiation patch 2 in face, radiation patch includes the first paster 21 of rectangle, is connected to the first paster end The second paster 22 in semicircular arc and be connected in semicircular arc the of second two ends of paster Three paster 23 and the 4th pasters 24.

Further, the first paster is connected on the arcwall face that the second paster is protruding.

Further, to be connected to the 3rd paster and the 4th paster protruding for two ends of the second paster On arcwall face.

Further, the junction point of the second paster and the 3rd paster is positioned at the centre of the 3rd paster, the second patch The junction point of sheet and the 4th paster is positioned at the centre of the 4th paster.

Further, the 3rd paster and the 4th paster are symmetrically distributed in the both sides of the first paster.

The antenna of the present invention has ultra-wide band, high-gain, accurate isotropic feature, can apply to various Different wireless communications environments.

It should be noted that in this article, the relational terms of such as first and second or the like is used merely to One entity or operation are separated with another entity or operating space, and not necessarily requires or imply Relation or the order of any this reality is there is between these entities or operation.And, term " includes ", " comprise " or its any other variant is intended to comprising of nonexcludability, so that include that one is The process of row key element, method, article or equipment not only include those key elements, but also include the brightest Other key elements really listed, or also include intrinsic for this process, method, article or equipment Key element.In the case of there is no more restriction, statement " including ... " key element limited, It is not precluded from there is also in including the process of described key element, method, article or equipment other identical Key element.

The above is only the detailed description of the invention of the application, it is noted that general for the art For logical technical staff, on the premise of without departing from the application principle, it is also possible to make some improvement and profit Decorations, these improvements and modifications also should be regarded as the protection domain of the application.
