Problems solved by technology

However, the traditional Yagi antenna is a narrow-band high-gain antenna, and its basic unit gain is not high, so many phase directors are needed, resulting in a large antenna (ie, long length)

Abstract

The invention discloses a broadband high-gain directional yagi antenna. The antenna comprises a reflecting plate, an antenna unit and a director, wherein the antenna unit is positioned above the reflecting plate and is spaced away from the reflecting plate along the vertical direction; the director is positioned above the antenna unit, is spaced away from the antenna unit along the vertical direction and is plate-shaped; each one of a first longitudinal edge and a second longitudinal edge of the director is a serrate edge for limiting a plurality of tooth parts and a plurality of tooth grooves. According to the broadband high-gain directional yagi antenna, the length of the edge of the director is increased to form a direction array, i.e., the efficiency of the director is increased, so that the size of the director and the integral size of the antenna are reduced, and broadband high gain is realized.

Description

technical field [0001] The invention relates to an antenna, in particular to a broadband high-gain directional Yagi antenna. Background technique [0002] The Yagi antenna is an end-fire antenna composed of an active dipole (usually a folded dipole), a passive reflector and multiple passive directors arranged in parallel. The Yagi antenna has good directivity, and the gain is higher than that of the dipole antenna, so the Yagi antenna is used for direction finding and long-distance communication. However, the traditional Yagi antenna is a narrow-band high-gain antenna, and its basic unit gain is not high, so many phase directors are required, resulting in a large antenna size (ie, long length). Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to propose a broadband high-gain directional Yagi antenna with small volume, wide ...
