Antenna Systems for Simultaneous Transmit and Receive (STAR) Applications
International Symposium on Microelectronics, 2017 Abstract Several novel wideband co-polarized circulator-less monostatic antenna and array designs for co-channel simultaneous transmit and receive (STAR) applications are presented. The monostatic STAR apertures are demonstrated first by utilizing multi-arm spiral antennas where a set of arms is used for transmitting (TX) and the other ...

A Concurrently Dual-Polarized, Simultaneous Transmit and Receive (STAR) Antenna
IEEE Transactions on Antennas and Propagation, 2020A concurrently dual-polarized, simultaneous transmit and receive (STAR) antenna system with high transmit (TX)-receive (RX) isolation is presented. The STAR antenna consists of four dual-polarized patches, two for TX and two for RX. The radiators are fed using a network consisting of four 90° hybrids and four 180° hybrids.

Wideband Monostatic Simultaneous Transmit and Receive (STAR) Antenna
IEEE Transactions on Antennas and Propagation, 2016A monostatic ultra-wideband simultaneous transmit and receive (STAR) antenna subsystem is introduced. An inherent geometrical symmetry of a four-arm spiral antenna and feeding rearrangement are exploited to achieve the simultaneous transmit (TX) and receive (RX) functionalities without any time, polarization, or frequency multiplexing.

Simultaneous transmit and receive (STAR) mobile testbed
2016 IEEE Radio and Wireless Symposium (RWS), 2016Simultaneous 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.

On wideband simultaneous transmit and receive (STAR) with a single aperture
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016Multi-arm spiral antennas have not only ability to radiate multiple frequency independent modes [1,2], but also inherent ability to act as monostatic co-channel simultaneous transmit and receive (STAR) apertures. Four-arm spirals are herein used for demonstrating this capability.

Wideband Antenna Array for Simultaneous Transmit and Receive (STAR) Applications
IEEE Antennas and Wireless Propagation Letters, 2017Design and performance of a nonscanning antenna array with wideband simultaneous transmit and receive capability are discussed. The proposed configuration utilizes a four-arm spiral antenna as a unit cell to achieve high isolation between transmit (TX) and receive (RX) ports and decent far-field performance.

Simultaneous Transmit and Receive (STAR): Circulators Versus Nonreciprocal Antennas
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019Desired antenna and front-end for simultaneous transmit and receive systems in addition to nonlinear and/or time variant nonreciprocal antennas are reviewed. The STAR system requirements in terms of antennas and front-end are investigated. Then, the properties of some proposed techniques for nonreciprocal antennas and circulator-based systems are ...
