High isolation in antenna arrays for simultaneous transmit and receive
2013 IEEE International Symposium on Phased Array Systems and Technology, 2013Simultaneous transmit and receive requires extremely high isolation between the transmitters and receivers. By designing an antenna array to have high isolation between elements, it is possible to enable simultaneous transmit and receive at the same frequency.

Wideband simultaneous transmit and receive (STAR) bi-layer circular array
2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015The main challenge with the full-duplex simultaneous transmit and receive (STAR) systems is achieving high isolation over a wide bandwidth while preserving identical (or similar) radiation patterns in both, the transmitting and receiving modes. In this paper, a novel low profile wideband bi-layer STAR circular array configuration is presented.

Shared Aperture Simultaneous Transmit and Receive Architecture for Reflectarray Antennas
2021 IEEE-APS Topical Conference on Antennas and Propagation in Wireless Communications (APWC), 2021A reflectarray aperture is a planar surface that mimics the parabolic reflector by using a doubly periodic array of carefully designed scatterers. Reflectarray antennas are rapidly becoming an attractive alternative to the traditional parabolic reflector systems due to the primarily application driven requirements and advantages such as size, weight ...

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.

Bi-Static Simultaneous Transmit And Receive (STAR) Antenna Array System
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019Bi-static, dual-polarized antenna array subsystem with high isolation between transmitting (TX) and receiving (RX) ports is proposed. Each array consists of eight active patch antenna elements built on a single layer substrate. Microstrip and substrate integrated waveguide (SIW) feed networks are used to excite broadside and scanned beams.

Wideband dual-mode monostatic simultaneous transmit and receive antenna system
2016 IEEE International Symposium on Antennas and Propagation (APSURSI), 2016A novel wideband monostatic simultaneous transmit and receive (STAR) antenna system based on eight-arm equiangular spiral aperture is proposed. The eight-arm STAR spiral is configured such that four arms are used for transmitting and the other four arms for receiving.

High-Directivty Broadband Simultaneous Transmit and Receive (STAR) Antenna System
2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018A broadband, circularly polarized (CP), and high-directivity STAR reflector antenna system is proposed. The high system isolation is achieved by mounting well-designed CP receiving (RX) and transmitting (TX) antennas with high front-to-back ratio (F/B) back-to-back.

Simultaneous transmit and receive antenna isolation improvement in scattering environments
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014Simultaneous transmit and receive (STAR) systems require high isolation between the transmitter and receiver to avoid self-interference. Antenna isolation degradation stems from errors in the physical construction and beamformer design, as well as reflections from scattering objects in the environment.

Wideband antenna array for Simultaneous Transmit and Receive (STAR) applications
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014A wideband antenna array for Simultaneous Transmit and Receive (STAR) applications is presented. The design is comprised of a ring array of TEM horns, and a monocone at the array's center. When the array is phased with the first order circular mode, it is isolated from the monocone. Thus, the array may be used in reception while the monocone is used in
