Abstract

The invention relates to a substrate integrated waveguide slot antenna. The antenna comprises a microstrip substrate; an upper-layer patch which is attached to the upper surface of the microstrip substrate, wherein a plurality of upper-layer radiation slots are formed in the upper-layer patch to form an upper-layer slot radiation array plane; a lower-layer patch which is attached to the lower surface of the microstrip substrate, wherein a plurality of lower-layer radiation slots are formed in the lower-layer patch to form a lower-layer slot radiation array plane; a plurality of metal via holeswhich are arranged to form a rectangle, wherein the upper-layer slot radiation array surface and the lower-layer slot radiation array surface are both arranged in the rectangle formed by arranging the metal via holes, and each metal via hole respectively passes through the upper layer patch, the microstrip substrate and the lower layer patch. The omnidirectional antenna is excellent in performance, low in weight, low in cost and low in processing difficulty, and 360-degree omnidirectional beam radiation can be realized when only a single antenna is used.

Description

technical field [0001] The invention relates to a waveguide slot antenna, in particular to a substrate-integrated waveguide slot antenna, which belongs to the technical field of antenna design. Background technique [0002] In the field of modern mobile communication, with the continuous development of the communication industry, more and more communication devices are loaded on the mobile communication carrier. "Therefore, reducing the space occupied by communication equipment as much as possible and improving the performance of communication equipment as much as possible have become the goals pursued at present." [0003] The commonly used form of waveguide slot antenna is traveling wave array antenna. However, the existing waveguide slot antenna still has the disadvantages and limitations of heavy weight, complex structure, difficult processing, and high manufacturing cost. [0004] Under this background, the present invention proposes a design idea of ​​a novel substra...
