POLARIZATION ADJUSTABLE APPARATUS APPLIED FOR MOBILE COMMUNICATIONS AND M/W LINK SYSTEM

摘要

PURPOSE: A polarization changing device for mobile communications and microwave relay system is provided to change the polarization of a service antenna by tracking polarization in real time for maximal received signal strength using a reference antenna. CONSTITUTION: Input patterns and output patterns of first and second dipoles in a standard antenna are formed in an input-output fixing plate. Variable coupling parts(210,310) output combined signals having changed polarization. Transfer mechanisms(220,320) are composed to transfer a moving coupler. The transfer mechanism drives a motor according to control signals of a control module. A service antenna polarization variable module outputs signals received from first and second dipoles of a service antenna into polarization converted service signals. A control module(400) outputs control signals for changing the polarization of the service antenna.
