Title: Low sidelobe antenna with beams steerable in one direction

Abstract: An antenna for scanning beams in only one common angular direction or angular path includes feed elements each providing a component beam and fixed beam combiners for combining the component beams into fixed beams. The fixed beam combiners combine the component beams in a first angular direction to form the fixed beams. Variable beam combiners combine the fixed beams into scanning beams. The variable beam combiners combine the fixed beams into the scanning beams to scan the scanning beams in a second common angular direction.
