Multi-band antenna element with integral faraday cage for phased arrays

摘要

An antenna structure and method is disclosed. A feed line is electromagnetically coupled to a conductive resonator. Further a faraday cage is operable to shield the conductive resonator and the feed line. The faraday cage comprises an electromagnetically-shielding ground plane coupled to a plurality of conductive strips by at least one conductive via.
