Abstract

A two-dimensional (2-D) beam steerable phased array antenna is presented comprising a continuously electronically steerable material including a tunable material or a variable dielectric material, preferred a liquid crystal material. A compact antenna architecture including a patch antenna array, tunable phase shifters, a feed network and a bias network is proposed. Similar to the LC display, the proposed antenna is fabricated by using automated manufacturing techniques and therefore the fabrication costs are reduced considerably.
