Abstract:
1. An antenna system for mitigating a multi-path effect on a radio frequency (RF) signal received by a single antenna and for providing a conditioned signal to a receiver, said system comprising: a splitter electrically connectable to the single antenna wherein said splitter splits the RF signal received by the single antenna into a first non-phase shifted signal and a second non-phase shifted signal; a variable phase shifter electrically connected to said splitter for receiving the second non-phase shifted signal, wherein said phase shifter phase shifts the second non-phase shifted signal to produce a first phase shifted signal and a second phase shifted signal that is different from the first phase shifted signal; a combiner having inputs electrically connected to said splitter and said variable phase shifter, said combiner receives and combines the first non-phase shifted signal and the first phase shifted signal to produce a first conditioned signal, and said combiner receives and combines the first non-phase shifted signal and the second phase shifted signal to produce a second conditioned signal; and a quality examiner circuit electrically connected to an output of said combiner to receive the first and second conditioned signals, with said quality examiner circuit configured to determine which of the conditioned signals has a highest quality, and wherein said quality examiner circuit provides the one of the first and second conditioned signals determined to have the highest quality to the receiver.
