Photonics for simultaneous transmit and receive

2011 IEEE MTT-S International Microwave Symposium, 2011
Many systems would benefit from the ability to transmit and receive signals within the same frequency band from the same aperture and at the same time. A key technology breakthrough enabling this simultaneous transmit and receive (STAR) capability is the recent development of a transmit-isolating photonic receive (TIPRx) link that functions both as the

Wideband Quasi-Monostatic Simultaneous Transmit and Receive Reflector Antenna

IEEE Transactions on Antennas and Propagation, 2020
A dual polarized quasi-monostatic simultaneous transmit and receive (STAR) antenna system operating over 2:1 bandwidth with high isolation, co-polarized transmitting (TX)/receiving (RX) radiation, and high TX gain is proposed. The TX antenna is apex matched parabolic reflector illuminated by a coaxial cavity feed.

Simultaneous transmit and receive (STAR) mobile testbed

2016 IEEE Radio and Wireless Symposium (RWS), 2016
Simultaneous Transmit and Receive (STAR) systems typically utilize multiple cancellation layers to improve system isolation and avoid self-interference. The design of these different layers must be evaluated both individually and as a whole to determine their effectiveness in various environments.
