Abstract: A microwave prism is used to repoint an operational Direct-to-Home (DTH) or Very Small Aperture Terminal (VSAT) reflector antenna as part of a ground terminal to receive (or transmit) signals from a different satellite or orbital position without physically moving the reflector or the feed horn antenna. The microwave prism operates by shifting the radiated fields from the horn antenna generally perpendicular to the focal axis of the parabolic reflector in order to cause the main beam of the reflector to scan in response. For an existing reflector antenna receiving signals from an incumbent satellite, a prism has been designed to be snapped into place over the feed horn and shift the fields laterally by a calibrated distance. The structure of the prism is designed to be positioned and oriented correctly without the use of skilled labor.

Abstract: Disclosed is a vertical RF launch mechanism for installing an RF cable onto an antenna PCB. The mechanism includes a cutout formed in the PCB whereby the cutout has interlocking tabs and an inner conductor receptacle formed in one interior edge. Installed on this interior edge is a vertical clip that has two tabs and a cylindrical outer conductor receptacle. The design of the cutout and the clip allows an RF cable to be installed so that it is vertically mounted to the PCB, provides a high-quality coupling for both the inner and outer conductors of the RF cables. It enables the soldering for both the inner and outer conductors to be done from the same side of the PCB. It also provides for a smaller cutout relative to conventional RF PCB launches, enabling a higher density placement of RF cable launches on a given PCB, providing for ultra-dense antenna designs.
