Title:
LOW COST CABLELESS GROUND STATION ANTENNA FOR MEDIUM EARTH ORBIT SATELLITE COMMUNICATION SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2015/084464
Kind Code:
A3
Abstract:
A ground station antenna including a torus shaped reflector having multiple feed points along a focal arc in front of the reflector. The ground station antenna includes transceiver feeds having their electrical phase centers located on the focal arc and supported by a rotating feed platform. The transceiver feeds are configured to simultaneously track rising and falling satellites when the platform rotates. The ground station antenna further includes a wireless power receiver coupled to the transceiver feeds to power the transceiver feeds. The ground station antenna further includes a wireless signal interface coupled to the transceiver feeds to communicate signals with a base unit to perform subsequent processing.
