A Concurrently Dual-Polarized, Simultaneous Transmit and Receive (STAR) Antenna

IEEE Transactions on Antennas and Propagation, 2020
A 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, 2016
A 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.

Wideband Antenna Array for Simultaneous Transmit and Receive (STAR) Applications

IEEE Antennas and Wireless Propagation Letters, 2017
Design 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.

A Compact, Monostatic, Co-Circularly Polarized Simultaneous Transmit and Receive (STAR) Antenna With High Isolation

IEEE Antennas and Wireless Propagation Letters, 2020
A compact, high-isolation, monostatic, co-circularly polarized (CP) simultaneous transmit and receive (STAR) antenna with similar radiation patterns is presented. The proposed antenna system consists of a sequentially rotated array (SRA) of four dual-polarized antenna elements and two quadrature feeding networks.

Simultaneous Transmit and Receive (STAR): Circulators Versus Nonreciprocal Antennas

2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019
Desired 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 ...

Monostatic Copolarized Simultaneous Transmit and Receive (STAR) Antenna by Integrated Single-Layer Design

IEEE Antennas and Wireless Propagation Letters, 2019
In this letter, a monostatic and cochannel simultaneous transmit and receive (STAR) antenna with identical circularly polarized radiations of transmitting (TX) and receiving (RX) channels is designed using a thin single-layer substrate. Four concentrically arranged microstrip radiating elements are properly excited by two sets of feeding networks: the ...

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.

Wideband simultaneous transmit and receive (STAR) circular array system

2016 IEEE International Symposium on Phased Array Systems and Technology (PAST), 2016
A wideband simultaneous transmit and receive (STAR) dual-layer circular array is considered to handle the space limitation and efficient use of wireless spectrum. The proposed STAR aperture configuration is composed of upper- and lower-layer circular arrays, where one works as transmitting and the other as receiving antenna. Each array consists of four
