Abstract

The invention relates to a dual-band high-gain directional antenna with a structure symmetric about an original point. The directional antenna comprises a round metal pattern symmetric about the original point and three feeding points, wherein the three feeding points are respectively arranged at a central position of the round metal pattern and two end point positions of the diameter, the diameter where three feeding points are located are coincided with a symmetric axis of the round metal pattern, and the directional antenna is used for emitting and receiving an electromagnetic wave signal in a first frequency band or a second frequency band. By the dual-band high-gain directional antenna, different frequency bands can be selected, the conditions of strong interference and noisy channels are avoided, so that a communication signal is transmitted in a high-gain way.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dual-band high-gain directional antenna with a symmetrical structure around the center of a circle. Background technique [0002] Directional antenna refers to an antenna that transmits and receives electromagnetic waves particularly strongly in one or several specific directions, while transmitting and receiving electromagnetic waves in other directions is zero or extremely small. The purpose of using a directional antenna is to increase the effective utilization of radiation power, increase confidentiality, or enhance signal strength to increase anti-interference ability. [0003] In practical applications, the channel condition of the directional antenna is relatively bad due to the strong interference in the environment, which leads to the decrease of the gain of the directional antenna. This decrease in gain is especially obvious when there is a single-band ...
