Abstract
Technologies for a wide-band linked-ring antenna element covering two adjacent K-band military and/or commercial receive bands are provided. The antenna element comprises a linked-ring conductive resonator that is electromagnetically coupled to at least one feed line. The conductive resonator and feed line are further surrounded by a Faraday cage that is conductively coupled to an electromagnetically-shielding ground plane and operable to shield the conductive resonator and the feed line.
