Title:
MULTIPLE POLARIZATION LOUDSPEAKER ANTENNA EMPLOYING ELECTRICALLY-CONTROLLED SWITCHING TECHNIQUE
Document Type and Number:
WIPO Patent Application WO/2020/124952
Kind Code:
A1
Abstract:
The present invention relates to the technical field of communication antennas. Disclosed is a multiple polarization loudspeaker antenna employing an electrically-controlled switching technique. The loudspeaker antenna comprises a loudspeaker antenna main body, a polarization controller and a polarization switching device. A control module controls a linear polarization control and generation module, a circular polarization control and generation module and a polarization selection module to cause the loudspeaker antenna to operate in a horizontally polarized mode, a vertically polarized mode, a counterclockwise circularly polarized mode or a clockwise circularly polarized mode. The loudspeaker can realize a quick switch between different polarization modes, and the switch is electrically controlled rather than performed by manually replacing the antenna. Using the antenna of the present invention can effectively shorten test time, reduce the number of times a tester needs to replace antennas, and more accurately measure characteristics of a device under test in various polarization modes.
