Abstract
The application discloses an antenna, including a medium plate, radiation paster, a feeder and a ground plate. The radiation paster and the feeder are formed on the upper surface of the medium plate. The ground plate is formed on the lower surface of the medium plate. The radiation paster is electrically connected to the feeder. One side, facing the medium plate, of the ground plate is provided with a recessed rectangular cavity. The antenna has a high antenna bandwidth, a simple structure, a low profile, and a wide application prospect in radar and communication systems.
Description
Technical field
The application belongs to wireless communication technology field, particularly relates to a kind of antenna.
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 a kind of antenna, 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 antenna, including dielectric-slab, is formed at described dielectric-slab upper surface
Radiation patch and feed line and be formed at the earth plate of described dielectric-slab lower surface, described radiation is pasted
Sheet and described feed line are electrically connected with, and described earth plate is recessed towards the side of described dielectric-slab is formed with square
The cavity of shape.
Preferably, in above-mentioned antenna, described radiation patch is E shape paster.
Preferably, in above-mentioned antenna, between described earth plate and described dielectric-slab, pass through tin metal layer
Connect.
Preferably, in above-mentioned antenna, the material of described dielectric-slab is politef.
Compared with prior art, it is an advantage of the current invention that: the beamwidth of antenna height of the present invention, simple in construction,
Section is low, is with a wide range of applications at radar and communication system.
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 sectional view of antenna in the specific embodiment of the invention；
Fig. 2 show the top view of antenna 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 and Fig. 2, antenna, including dielectric-slab 1, the spoke that is formed at described dielectric-slab upper surface
Penetrate paster 2 and feed line and be formed at the earth plate 3 of described dielectric-slab lower surface, described radiation patch
2 are electrically connected with described feed line, and described earth plate 3 is recessed towards the side of described dielectric-slab is formed with square
The cavity 31 of shape.
Further, described radiation patch 2 is E shape paster.
Further, it is connected by tin metal layer 4 between described earth plate 3 with described dielectric-slab 1.
Further, the material of described dielectric-slab is politef.
The beamwidth of antenna height of the present invention, simple in construction, section are low, have extensively at radar and communication system
Application prospect.
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.
