Abstract
A liquid crystal antenna and a method of beamforming of electromagnetic waves are provided. The method includes: receiving by a feeding circuit board a feeding signal to form a feeding electromagnetic wave; applying a plurality of bias voltages respectively between a ground plane and a plurality of patch antenna units of a liquid crystal modulation structure to form an amplitude interference pattern, wherein a liquid crystal layer of the liquid crystal modulation structure is disposed between the ground plane and the patch antenna units; and utilizing interference of the feeding electromagnetic wave and the amplitude interference pattern to form an electromagnetic beam, wherein the electromagnetic beam is directed to a specific angle, and an intensity and the specific angle of the electromagnetic beam are modulated according to the variations of the feeding electromagnetic wave and the amplitude interference pattern.
