Abstract
A lens antenna for multi-beam scanning is presented. The antenna system is composed of a feed linear array, a binary diffractive dielectric lens (BDL) and a voltage-controlled ferroelectric lens (VCFL). The feeds at different offset foci of the BDL generate receiving/radiating beams pointing to different angles; the VCFL made of ferroelectric slabs generate variable linear phase shift when loaded with corresponding DC voltages to steer the scanning multiple beams.
