摘要： Antenna units, antenna systems and polarizing systems provide polarization diversity to leaky-wave antennas. An antenna unit comprises a rat-race coupler having a summation port, a difference port and two output ports. Each one of a pair of composite right/left-handed (CRLH) leaky-wave antennas (LWA) is connected at one end to a respective one of the output ports of the rat-race coupler. An inductive stub is implemented between the CRLH LWAs for connecting the CRLH LWAs to a grounded via. Various polarizations are obtained by injecting a radio-frequency (RF) signal in the summation or difference port of the rat-race coupler, or in both ports. System variants include various devices and assemblies for injecting RF signals in the antenna unit. One such variant includes a polarizing system having a switched matrix for directing a signal according to various intended polarizations.
