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

Wideband simultaneous transmit and receive (STAR) bi-layer circular array

2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015
The 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.

Phased Array Antenna for Bi-Static Simultaneous Transmit and Receive (STAR) system

2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020
Bi-static simultaneous transmit and receive shared phased array aperture with wide-angle beam steering is discussed. Antenna system works over a narrow frequency range in K-band and has $10\times 10$ circularly polarized stacked-patch antenna elements distributed in two 10×5 apertures for transmit and receive.

High-Directivty Broadband Simultaneous Transmit and Receive (STAR) Antenna System

2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018
A 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.

Bi-Static Simultaneous Transmit And Receive (STAR) Antenna Array System

2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019
Bi-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 scanning array of spiral antennas for simultaneous transmit and receive (STAR)

2017 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2017
We present a low profile (λ LOW /8) wideband slot spiral antenna array with high transmit/receive (Tx/Rx) isolation and scanning capability for STAR systems. To our knowledge, this is the first wideband STAR array with circular polarization and scanning capability.

Ultra-wideband circularly-polarized simultaneous transmit and receive (STAR) antenna system

2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015
This paper presents a novel circularly-polarized simultaneous transmit and receive (STAR) monostatic antenna system based on the four-arm spiral-helix antenna. The four-arm spiral is configured such that two arms are used for transmitting and the other two arms for receiving. Microstrip feeds with impedance transformers are used to feed the two two-arm

An Interior Parasitic Patch Antenna with Wide Isolation Bandwidth for Simultaneous Transmit and Receive (STAR)

2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019
A microstrip patch antenna with a 180° hybrid coupler and parasitic patches under radiating patches is proposed for STAR applications. The antenna geometry and isolation improving methods are explained. Simulation results of S-parameters, gain, antenna efficiency, and radiation patterns, are presented.
