High data rate satellite communications in Ka-band are an important and ongoing area of research and development. Especially compact antennas with high gain are of interest for bidirectional land mobile scenarios. In this paper, we describe a volume-efficient Cassegrain reflector antenna fed from a novel PCB-based multimode monopulse feed chain. The structure provides a dual circular polarisation...
This publication presents a leaky-wave antenna panel comprised of a dual-layer partially reflective surface intended for transmit and receive operations in Ka-band. Several of these panels are installed on the outdoor-unit of a low-profile user-terminal intended for satellite communication on the move during emergency scenarios. Given the widely separated up- and downlink-frequencies in Ka-band, the...
The increasing interest in bi-directional mobile high data rate satellite communications in Ka-band necessitates the development of dedicated antenna tracking systems and feeds. In this paper we describe a compact feed structure based on printed circuit boards for a mobile satellite communications ground terminal with a Cassegrain reflector antenna. The novel structure provides a dual circular polarisation...
