Abstract: A dual polarization current loop radiator realized with a via, probe, or exposed coaxial feed using part of a vertical metal structure of the radiator to guide current to a feed point of a horizontal metal plate capacitively coupled to the vertical metal structure is described. The vertical metal structure may be either stamped and attached to the ground plane or it can be formed along with metal backplane structure of the radiator. The top of the vertical metal piece is separated from the horizontal metal plate by a predetermined distance dielectric spacing. The spacing may be realized either a thin dielectric core or a non-conductive adhesive material.

Abstract: An assembly comprises a first subassembly, a second subassembly, and a conductive grounding element. The first subassembly comprises a first module comprising a first ground plane and a first conductive region in operable communication with the first ground plane. The second subassembly comprises a second module comprising a second ground plane distinct from the first ground plane and a second conductive region in operable communication with the second ground plane. The first and second subassemblies attach to each other along a seam. The conductive grounding element comprises an electrically conductive material including a first portion disposed adjacent to the first conductive region and a second portion disposed adjacent the second conductive region. The conductive grounding element is configured to fill one or more gaps in the seam and to operably couple together the first and second ground planes of the first and second subassemblies into a third common ground plane.

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.

Abstract: An array antenna includes a modular, multi-layer, multi-balun board structure for use in feeding a dual polarization radiating element. In some embodiments, contacts on a multi-balun board structure may be directly conductively coupled to corresponding feed points of a dual polarization radiating element during antenna assembly. The multi-balun board structure may be inserted into an opening within an aperture board of an array antenna before the contacts are secured to the feed points. Dual balun board structures may be provided for some or all of the radiating elements on the aperture board.
