Abstract
An antenna includes a reflector having a first axis, a second axis, a focal zone that is about parallel to the first axis, and a focal point located within the focal zone. A transmit feed is located at the focal point, and at least one receive feed is located within the focal zone. The transmit feed is part of a bidirectional feed that includes an integral receive feed. The bidirectional feed transmits and receives an RF signal carrying digital information signals to and from a first satellite, such as an FSS satellite, and each respective receive feed receives a signal from satellite, such as a DBS satellite.
Claims6
An antenna, comprising:
- a reflector having a focal zone and a focal point located within the focal zone;
- a transmit feed located about at the focal point;
- and
- at least one receive feed located within the focal zone,
- wherein the transmit feed is part of a bidirectional feed, the bidirectional feed including a receive feed that is integral with the transmit feed and a separate transmit feed and a separate receive feed, the separate receive feed being located immediately adjacent to the separate transmit feed within the focal zone.
