Wide-band linked-ring antenna element for phased arrays

摘要

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 (100) comprises a linked-ring conductive resonator (102) that is electromagnetically coupled to at least one feed line (104). The conductive resonator (102) and feed line (104) are further surrounded by a Faraday cage (106) that is conductively coupled to an electromagnetically-shielding ground plane (110) and operable to shield the conductive resonator (102) and the feed line (104).
