Abstract

The invention relates to a microstrip quasi-yagi antenna, which comprises a double-sided microstrip quasi-yagi antenna and a director loaded on the double-sided microstrip quasi-yagi antenna, whereinthe director comprises a rectangular patch and a right-angle microstrip line, the rectangular patch is loaded at the tail end of the excitation pole of the double-sided microstrip quasi-yagi antenna,the rectangular patch is used for expanding the beam width and realizing beam deflection, the right-angle microstrip line and the outer right angle of the rectangular patch are mounted in a clearancefit manner, and the right-angle microstrip line is used for further expanding the beam width and improving the gain of the antenna. By adopting the method, the size of the microstrip quasi-yagi antenna can be greatly reduced under the condition of beam deflection guidance.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a microstrip quasi-Yagi antenna. Background technique [0002] With the rapid development of wireless communication technology, as the most basic component - antenna, some special performances are constantly optimized and improved. For example, some highly directional local positioning systems (LPS), wireless sensor networks, and some scenarios in the fifth-generation mobile communication technology that are more and more widely used now require a highly directional and compact size or Small size antenna type. The microstrip quasi-Yagi antenna can meet such requirements. It is composed of a Yagi antenna with strong directivity and high gain but bulky and a low-profile, easy-to-process microstrip antenna. Combining the advantages of the two, it also has the characteristics of wider bandwidth and is more conducive to array formation, which greatly expands the applicati...
