Abstract
A frequency modulated continuous wave (FMCW) radar antenna that may provide isolation between the transmit (Tx) antenna and the receive (Rx) antenna based on the arrangement of the transmit elements and the receive elements. The transmit antenna elements for the antenna of this disclosure may be orthogonally fed, e.g., different by 90 degrees, compared to the receive antenna elements. For example, for horizontally polarized receive antenna elements, the transmit elements may be vertically polarized, or vice versa. The cross-polarized antenna elements may cause attenuation of surface waves between the Tx and Rx antennae. A low insertion loss 90-degree polarizer layer over one of the transmitter antenna, or the receiver antenna, to convert either the transmitted signals or the received reflections by 90-degrees so the reflected signal matches the polarization of the receiver antenna.
