    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.

    Abstract: Systems and methods which provide enhanced isolation for receivers using relatively simple and inexpensive modifications or additional circuitry at a receiving station. Embodiments augment a primary antenna of a receiving station with a correlated heterogeneous antenna element. Augmented antenna systems of embodiments provide an appreciable increase in front-to-back isolation with respect to desired signals received at a receiving station. Such augmented antenna systems are particularly useful in a high interference environment, such as an interference limited environment as may be experienced at the edge of two Single Frequency Networks (SFNs). For example, embodiments of an augmented antenna system may be utilized in situations in which positive carrier to noise ratio (C/N) conditions are present (e.g., more signal than noise is present in the desired signal and more signal than noise is present in the interfering signal).
