Anti-metal interference back-mounted antenna

Abstract

This utility model discloses an anti-metal interference back-clamp antenna, specifically relating to the field of antenna technology. It includes an anti-interference sleeve, with an antenna core fixedly connected to the inner wall of the sleeve. An anti-interference covering assembly is installed on the outer wall of the antenna core near its top. The anti-interference covering assembly includes: a wire core end fixedly connected to the outer wall of the antenna core near its top; an anti-interference cover fixedly connected to the outer wall of the wire core end; and multiple anti-interference covers arranged equidistantly in a circular pattern on the outer wall of the multiple anti-interference covers. Connecting strips are fixedly connected between adjacent anti-interference covers. This utility model uses an anti-interference covering assembly, and the anti-interference covers provide external anti-metal interference protection to the wire core end and antenna core above. Multiple anti-interference covers and multiple connecting strips provide better, wider-range anti-metal interference protection to the wire core end and antenna core.
