摘要

The terrestrial station antenna includes a torus-shaped reflector having a plurality of feed points along a focus arc in front of the reflector. The ground station antenna includes transceiver feeds supported by a rotatable feed platform and having its own electrical phase centers located on the focus arc. The transceiver feeds are configured to track rising and falling satellites simultaneously when the platform rotates. The terrestrial station antenna further includes a wireless power receiver coupled to the transceiver feeds to power the transceiver feeds. The terrestrial station antenna further includes a wireless signal interface coupled to the transceiver feeds for communicating signals with the base unit to perform subsequent processing.;
