Abstract

This paper presents the experimental demonstration and the far field pattern characterization of an optically controlled phased array antenna. It operates between 2.5 and 3.5 GHz and is made of 16 radiating elements. The optical control uses a 2D architecture based on free space propagation and on polarization switching by N spatial light modulators of pxp pixels. It provides 2^N-1 time delays values and an analog control of the 0 to 2(pi) phase for each of the pxp signals feeding the antenna (N equals 5, p equals 4).
