Abstract: An electrically scanned lens antenna for two dimensional scanning is presented. The antenna system is composed of a (N × 1) feed 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 beams pointing to different angles to perform beam scanning in one dimension; the VCFL made of ferroelectric slabs which show linear permittivity gradient when loaded with corresponding DC voltages generate linear phase shift to steer the beam in the other dimension.
