ABSTRACT:
A wireless communication system that utilizes a circularly polarized transmitting antenna with dual orthogonal circularly polarized receiving antenna. According to some embodiments, the present invention provides a wireless communication system that includes a first transmitting antenna capable of transmitting first signals having a first type of circular polarization. The transmitting antenna is located at a first location. The system also includes a first receiving antenna capable of receiving second signals having a second type of circular polarization, where the second type of circular polarization is orthogonal to the first type of circular polarization. The system further includes a second receiving antenna capable of receiving third signals having the first type of circular polarization, and the first receiving antenna and the second receiving antenna are both located at a second location. In other embodiments, the present invention may also utilize microwave antenna systems for transmitting a circularly polarized signal and for receiving two orthogonally circularly polarized signals.
