Description
Technical field
The application belongs to wireless communication technology field, particularly relates to a kind of microstrip antenna.
Background technology
Wireless domain is worked out for the different market demands and application model different standards, as being applied to the IEEE802.16 standard of WLAN, also known as micro-wave access global inter communication (WorldInteroperabilityforMicrowaveAccess, WiMAX).Wherein, the mobile WiMAX in IEEE802.16e comprises 2.3GHz and 2.7GHz frequency range.
For the Wireless Telecom Equipment being applied to wireless domain, generally need to be designed to smaller size smaller, and antenna is the assembly of its indispensability, therefore reduces a solution that antenna volume is reduction Wireless Telecom Equipment volume.Existing microstrip antenna often adopts the shapes such as rectangle, circle and annular, but all needs larger area.Thus, how at the band limits meeting WiMAX standard, the microstrip antenna designing WiMAX with less area is then a major challenge, is also the target that current industry is badly in need of improving.
Utility model content
The purpose of this utility model is to provide a kind of 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 microstrip antenna, comprise dielectric layer, be formed at described dielectric layer upper and lower surface and identical the first radiation patch of shape and the second radiation patch respectively, described first radiation patch and the second radiation patch are the paster of end to end annular, described first radiation patch and radiation patch are 90 ° and intersect, and described first radiation patch is connected a coaxial feeder respectively with the second radiation patch.
Preferably, in above-mentioned microstrip antenna, described first radiation patch comprise two parallel straight flange radiant sections and symmetry be connected to described straight flange radiant section two ends in heart-shaped left radiant section and right radiant section.
Preferably, in above-mentioned microstrip antenna, described left radiant section and right radiant section offer a breach respectively in symmetric position.
Preferably, in above-mentioned microstrip antenna, the material of described dielectric layer is polytetrafluoroethylene.
Compared with prior art, the utility model has the advantage of: the utility model utilizes coaxial feeder two-terminal feeding, be respectively equipped with radiation patch in the upper and lower both sides of dielectric layer, can realize double-circle polarization, structure is simple and size is little.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Figure 1 shows that the structural representation of microstrip antenna in the utility model specific embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be described in detail the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
Shown in ginseng Fig. 1, microstrip antenna comprises dielectric layer 1, is formed at described dielectric layer upper and lower surface and identical the first radiation patch 2 and the second radiation patch 3 of shape respectively, described first radiation patch 2 and the second radiation 3 paster are the paster of end to end annular, described first radiation patch and radiation patch are 90 ° and intersect, and described first radiation patch and the second radiation patch are connected a coaxial feeder 4 respectively.
Further, described first radiation patch comprise two parallel straight flange radiant sections 21 and symmetry be connected to described straight flange radiant section two ends in heart-shaped left radiant section 22 and right radiant section 23.
Further, described left radiant section and right radiant section offer a breach 221 respectively in symmetric position.
Further, the material of described dielectric layer is polytetrafluoroethylene.
The utility model utilizes coaxial feeder two-terminal feeding, and be respectively equipped with radiation patch in the upper and lower both sides of dielectric layer, can realize double-circle polarization, structure is simple and size is little.
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.
