Abstract
The invention discloses a slot-coupled planar antenna, which comprises a first dielectric plate and a second dielectric plate arranged vertically at an interval, wherein first supporting rods are supported between the first dielectric plate and the second dielectric plate; a radiation patch is arranged on the upper surface of the first dielectric plate; a grounding part is arranged on the upper surface of the second dielectric plate; a butterfly-shaped slop extending along a first direction is opened in the grounding part; the lower surface of the second dielectric plate is provided with a microstrip feeder extending along a second direction; and the second direction is vertical to the first direction. The slot-coupled planar antenna has the advantages that a dielectric plate is arranged above the radiation patch in a covering mode, thereby playing a protection role on the radiation patch; as the square radiation patch is adopted, the symmetry is good, and the manufacturing is simple; a wide bandwidth is acquired through coupling between the radiation patch and the slot in the grounding part; and the antenna has the advantages of wide bandwidth, easy integration, high mechanical strength and the like.

Background technology
Flat plane antenna has the advantages such as size is little, lightweight, section is low, is widely used in radar and communicates
Field.1985, Pozar proposed a kind of flat plane antenna using rectangular aperture to carry out couple feed.This
Plant antenna and isolated radiating layer and feed layer by earth plate, eliminate impact each other, and overcome
The shortcomings such as the parasitic radiation of the tradition inductive effect brought of feeding classification and feeding network.But, its bandwidth
Narrower, its application is limited in a lot of occasions.For broadening flat plane antenna bandwidth effectively, carry out both at home and abroad
Substantial amounts of research, foam or air as used multiple-layered patches structure, using dielectric constant close to 1.0 are situated between
Matter is made backing material, is changed feed structure and gap structure etc..
Summary of the invention
It is an object of the invention to provide a kind of slot-coupled flat plane antenna, with overcome of the prior art not
