Abstract
The application discloses circular patch microstrip antenna, including first dielectric plate and the second dielectric plate that sets up from top to bottom, it has the bracing piece to support between first dielectric plate and the second dielectric plate, be formed with circular shape radiation paster on the upper surface of first dielectric plate, should radiate paster symmetry along the first direction on and set up two curved first gaps, should radiate paster symmetry along the second direction in and be equipped with two curved second gaps, first direction and second direction are perpendicular, be formed with ground connection portion on the lower surface of second dielectric plate, be connected with the coaxial probe between radiation paster and the ground connection portion. The utility model discloses a bandwidth has been extended in the effectual exhibition of antenna, and the area of paster is little moreover, and the in -band ratio of gains is more 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, 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, be necessary to provide a kind of novel flat plane antenna.
Utility model content
The purpose of this utility model is to provide a kind of circular patch 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 circular patch microstrip antenna, comprise first medium plate setting up and down and second medium plate, support bar is supported with between described first medium plate and second medium plate, the upper surface of described first medium plate is formed with circular radiation patch, this radiation patch is along the first gap offering two arcs symmetrical on first direction, this radiation patch is along the second gap second direction being arranged with two arcs, described first direction is vertical with second direction, the lower surface of described second medium plate is formed with grounding parts, coaxial probe is connected with between described radiation patch and grounding parts.
Preferably, in above-mentioned circular patch microstrip antenna, described second gap is positioned at the space of the circle that described first gap surrounds.
Preferably, in above-mentioned circular patch microstrip antenna, described coaxial probe is positioned at the space that described second gap surrounds.
Preferably, in above-mentioned circular patch microstrip antenna, the material of described first medium plate and second medium plate is polytetrafluoroethylene.
Preferably, in above-mentioned circular patch microstrip antenna, described second gap hides the opening between described first gap.
Compared with prior art, the utility model has the advantage of: antenna of the present utility model effective broadening bandwidth, and the area of paster is little, in band, gain is more stable.

Shown in ginseng Fig. 1 and Fig. 2, circular patch microstrip antenna, comprise first medium plate 1 setting up and down and second medium plate 2, support bar 3 is supported with between first medium plate 1 and second medium plate 2, the upper surface of first medium plate 1 is formed with circular radiation patch 4, this radiation patch 4 is along the first gap 41 offering two arcs symmetrical on first direction, this radiation patch 4 is along the second gap 42 second direction being arranged with two arcs, first direction is vertical with second direction, the lower surface of second medium plate 2 is formed with grounding parts 5, coaxial probe 6 is connected with between radiation patch 4 and grounding parts 5.
Further, the second gap 42 is positioned at the space of the circle 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 polytetrafluoroethylene.
Further, the second gap 42 hides the opening between the first gap.
Antenna of the present utility model effective broadening bandwidth, and the area of paster is little, and in band, gain is more stable.
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.
