Abstract

The invention relates to a high-gain ultra-wideband directional antenna of an origin symmetric structure. The directional antenna comprises an original-symmetric round metal pattern and three feed points, wherein the three feed points are respectively located at the center and two ends of the round metal pattern; the diameters of the three feed points are superposed with a symmetric axis of the round metal pattern; and the directional antenna is used for transmitting or receiving electromagnetic wave signals from 2.5GHz to 8GHz. The directional antenna can select different frequency bands, avoid the conditions of strong interference and severe channels, and transmit communication signals with high gain.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a high-gain ultra-wideband 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 and affects the use. Contents of the invention [0004] Aiming at...
