Abstract
A transceiver circuit that includes multi-port antenna and transmitter and receiver circuit may transmit and receive polarized electromagnetic waves. The polarization of transmitted electromagnetic waves may be determined by adjusting gain and phase differences between multiple circuit paths in the transmitter circuit. In a similar fashion, the gain and phase of circuit paths in the receiver circuit may be adjusted to accommodate different polarizations of received electromagnetic waves.
