Method and apparatus for wireless communications and sensing utilizing a non-collimating lens

摘要

An antenna feed system capable of simultaneously transmitting and receiving in multiple frequency bands. In one embodiment, the feed system comprises a non-collimating lens attached to the emitting end of a broad-band antenna feed. The lens is positioned to receive and focus the broad-band wireless signals from any reflector configuration to any antenna feed. It is also positioned to transmit and focus the broad-band wireless signals from any antenna feed to any reflector configuration. A method for illuminating a reflector configuration through an antenna feed with the lens is disclosed. A wireless sensor system is also disclosed. In one embodiment, the non-collimating lens may be used as part of a wireless signal sensor unit used to increase or decrease the angular aperture of the sensor unit.
