Abstract
A multi-beam transmit/receive device comprises a Circular Polarization Frequency Selective Surface (CPFSS) unit, a transmit (Tx) flat array antenna assembly with multi-bean flat array antenna and a receive (Rx) flat array antenna assembly with multi-bean flat array antenna. The Tx multi-beam antenna is poisoned with respect to the CPFSS unit so that its transmission is configured to be reflected by the CPFSS unit to a reflector and to be reflected by the reflector in a defined direction and the Rx multi-beam antenna is poisoned with respect to the CPFSS unit so that transmission that hits the reflector from the defined direction and passes through the CPFSS unit focuses on the Rx multi-beam antenna.
