Abstract
An electronically scanned array (ESA) antenna includes a main line along which an electromagnetic traveling wave may propagate and a plurality of array elements distributed along the main line. Each of the plurality of array elements includes a branch line; an antenna radiator at one end of the branch line; an electronically controllable reflection phase shifter at the opposite end of the branch line; a directional coupler which couples energy between the main line and the branch line.
