Abstract
A multi-beam liquid crystal antenna and a method of multi-beamforming are provided. The method includes: providing a liquid crystal modulation structure; utilizing a feeding structure to receive a feeding signal and to generate substantially an equiphase feeding electromagnetic wave to patch antenna units of the liquid crystal modulation structure; generating, by the patch antenna units, first radiation intensities and second radiation intensities respectively when the patch antenna units are utilized to receive alternating-current (AC) voltages respectively, so that the liquid crystal modulation structure forms an amplitude interference pattern; and utilizing interference of the feeding electromagnetic wave and the amplitude interference pattern to form electromagnetic beams, in which arrangement positions of the first radiation intensities and the second radiation intensities corresponding to the amplitude interference pattern change an azimuth angle and a tilt angle of each of the electromagnetic beams.
