Abstract
The present invention relates to a compact beamforming module (10) for phased array antennas, comprising RF switches (12) and a plurality of phase shifters (20), each of which has at least one defected ground structure (26/27/18), by applying a thin film structure on any type of substrate (22). The beamforming module of the invention provides unique synergistic features and advantages, such as material selection independent of the substrate (22) type, ease of integration with semiconductor circuits, usability with high-power amplifiers to provide high EIRP antennas, and high space savings with cost-effectiveness.
