Abstract

An ultra-wideband antenna compatible with a WLAN system belongs to the field of wireless communication. The existing ultra-wideband antenna is not mature technologically and has crowded frequency spectrum. According to the ultra-wideband antenna compatible with a WLAN system, one side plate of a dielectric substrate (1) is printed with a micro-strip feeder (2) and an elliptical adjusting branch (3), the other side plate of the dielectric substrate (1) is printed with a metal patch (4) having an elliptic hole (5), the inside of the elliptic hole (5) is printed with a micro-strip adjust branch (6) and an elliptic metal patch (7) from outside to inside, and a metal connecting bridge (8) is arranged between the edge of the elliptic hole (5) and the periphery of the micro-strip adjust branch (6). Compatibility between the ultra-wideband antenna and the WLAN system is realized. The problem of crowded frequency spectrum can be fully solved through wide high frequency band. The ultra-wideband antenna has the advantages of low profile, compact structure, small weight, low cost, and easy integration.

Description

technical field [0001] The invention relates to an ultra-wideband antenna compatible with a WLAN system. Background technique [0002] Ultra-wideband antennas can realize communication, radar, navigation and electronic warfare transmission and reception at the same time, greatly reduce the volume and load of the antenna system, realize the optimal layout of the antenna system on the carrier, and effectively reduce the radar cross section of the antenna system. High point of technology. In recent years, with the opening of commercial applications of ultra-wideband technology teams, more and more ultra-wideband antennas are used in wireless communication systems, which has become a new research hotspot. [0003] However, the technical means of ultra-wideband antennas are not yet mature enough, and there is a problem of spectrum congestion. Contents of the invention [0004] The object of the present invention is to propose an ultra-wideband antenna compatible with a WLAN s...
