Abstract
The invention discloses a circular patch microstrip antenna. The circular patch microstrip antenna comprises a first dielectric plate and a second dielectric plate which are arranged up and down, wherein supporting rods are arranged between the first dielectric plate and the second dielectric plate in a supporting manner; a circular radiation patch is formed on the upper surface of the first dielectric plate; two arc-shaped first gaps are symmetrically formed in the radiation patch in a first direction; two arc-shaped second gaps are symmetrically formed in the radiation patch in a second direction; the first direction is perpendicular to the second direction; a grounding part is formed on the lower surface of the second dielectric plate; and a coaxial probe is connected between the radiation patch and the grounding part. According to the circular patch microstrip antenna, the bandwidth is effectively increased; and in addition, the patch is small in area while the in-band gain is relatively stable.
Description
Technical field
The application belongs to wireless communication technology field, particularly relates to a kind of circular patch microstrip 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 a kind of novel flat plane antenna is provided.
Summary of the invention
It is an object of the invention to provide a kind of circular patch microstrip antenna, with overcome of the prior art not
Foot.
For achieving the above object, the present invention provides following technical scheme:
The embodiment of the present application discloses a kind of circular patch microstrip antenna, including first medium setting up and down
Plate and second medium plate, support between described first medium plate and second medium plate and have a support bar, and described the
Being formed with the radiation patch of circle on the upper surface of one dielectric-slab, this radiation patch goes up symmetry in the first direction
Offer the first gap of two arcs, this radiation patch in a second direction on be arranged with two arcs
Second gap, described first direction is vertical with second direction, and the lower surface of described second medium plate is formed
Having grounding parts, connecting between described radiation patch and grounding parts has coaxial probe.
Preferably, in above-mentioned circular patch microstrip antenna, described second gap is positioned at described first seam
In the circular space that gap surrounds.
Preferably, in above-mentioned circular patch microstrip antenna, described coaxial probe is positioned at described second seam
In the space that gap surrounds.
Preferably, in above-mentioned circular patch microstrip antenna, described first medium plate and second medium plate
Material be politef.
Preferably, in above-mentioned circular patch microstrip antenna, described second gap hides in described first
Opening between gap.
Compared with prior art, it is an advantage of the current invention that: the effective broadening of antenna of present invention bandwidth,
And the area of paster is little, in band, gain is more stable.
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,

Shown in ginseng Fig. 1 and Fig. 2, circular patch microstrip antenna, including first medium plate 1 setting up and down
With second medium plate 2, supporting and have support bar 3 between first medium plate 1 and second medium plate 2, first is situated between
Being formed with the radiation patch 4 of circle on the upper surface of scutum 1, this radiation patch 4 goes up symmetry in the first direction
Offer the first gap 41 of two arcs, this radiation patch 4 in a second direction on be arranged with two arcs
Second gap 42 of shape, first direction is vertical with second direction, and the lower surface of second medium plate 2 is formed
Having grounding parts 5, connecting between radiation patch 4 and grounding parts 5 has coaxial probe 6.
Further, the second gap 42 is positioned at the circular space that the first gap surrounds.
Further, coaxial probe 6 is positioned at the space that the second gap 43 surrounds.
Further, the material of first medium plate 1 and second medium plate 2 is politef.
Further, the second gap 42 hides the opening between the first gap.
The effective broadening of antenna of present invention bandwidth, and the area of paster is little, and in band, gain is more steady
Fixed.
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.
