Abstract

The invention discloses an electric-control switching multi-polarization horn antenna, and relates to the technical field of a communication antenna. The horn antenna comprises a horn antenna body andalso comprises a polarization controller and a polarization switching device, wherein the control module is used for enabling the horn antenna to work in modes of horizontal polarization, vertical polarization, left-hand circular polarization or right-hand circular polarization by controlling a linear polarization control generation module, a circular polarization control generation module and apolarization selection module. By the antenna, rapid switching among different polarization modes can be achieved, and switching employs electric switching rather than artificial antenna replacement.With the adoption of the antenna, the test time can be effectively reduced, the frequency of replacing the antenna by a tester is reduced, and the characteristic of a tested device under various polarization modes is more accurately measured.

Description

technical field

[0001] The invention relates to the technical field of communication antennas, in particular to an electrically controlled switching multi-polarization horn antenna. Background technique

[0002] An antenna is an electromagnetic field energy converter that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. It belongs to the core component used to transmit or receive electromagnetic waves in radio equipment. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, which use electromagnetic waves to transmit information, need to rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires antennas.
