Abstract
An antenna system includes a first antenna operational to transmit a first radio-frequency signal, a second antenna operational to receive a second radio-frequency signal and receive the first radio-frequency signal, a first electromagnetic polarizer disposed between the first antenna and the second antenna and operational to change a polarization of the first radio-frequency signal, a second electromagnetic polarizer disposed between the first electromagnetic polarizer and the second antenna and operational to further change the polarization of the first radio-frequency signal, and a conductive ground plane disposed on a ground side of the first antenna and the second antenna. The conductive ground plane defines a gap between the first antenna and the second antenna. The gap extends under the first electromagnetic polarizer. The gap extends under the second electromagnetic polarizer. A horizontal component of the second polarization of the first radio-frequency signal is maintained across the gap.
