Abstract :
Limited electronic steering can be accomplished using a focusing reflective surface by changing the feed location or direction of incidence. In this paper we describe a method of electronic beam steering by using a tunable impedance surface. Since there are no moving parts or complicated feed networks, this method of reflective beam steering can have great utility for low-cost and lightweight scanning antennas.
