Abstract
A wideband dual-polarized current loop antenna element is provided having a ground tower and an antenna circuit integrated, such as within a multi-layer circuit board configuration. The antenna circuit includes feed conductors and element conductors, each of which are capacitively coupled to a top ground plane of the ground tower. The feed conductors are coupled to receive signals from coaxial feed lines coupled to the respective antenna element and element conductors are coupled to receive signals from adjacent antenna elements, such as in an antenna array configuration. The antenna element can further include one or more frequency selective surface (FSS) layers disposed proximate to the top ground plane of the ground tower and the antenna circuit. The ground tower, antenna circuit and one or more FSS layers can be formed to provide a low-profile antenna element having wide broadband performance.
