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.

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.

Wideband, scanning array for simultaneous transmit and receive

2018 International Applied Computational Electromagnetics Society Symposium (ACES), 2018
We present a low profile wideband spiral antenna array with high transmit/receive (Tx/Rx) isolation and beam steering capability for simultaneous transmit and receive (STAR) systems. STAR increases a channel's spectral efficiency by transmitting and receiving across the full bandwidth of a channel.

Simultaneous transmit and receive with digital phased arrays

2016 IEEE International Symposium on Phased Array Systems and Technology (PAST), 2016
A new architecture is proposed for achieving Simultaneous Transmit and Receive (STAR) with a digital phased array. We demonstrate how digital beamforming and cancellation enables adjacent transmitting and receiving sub-arrays to operate simultaneously in the same frequency band without a significant reduction in performance.

Simultaneous Transmit and Receive Spiral Antenna With Improved Isolation

IEEE Antennas and Wireless Propagation Letters, 2020
A wideband, monostatic simultaneous transmit and receive cocircularly-polarized spiral antenna with improved isolation is discussed. The topology with four arms is configured such that the opposite pairs of arms are used for transmit (TX) and receive (RX).

Active Excitation Tuning for Simultaneous Transmit and Receive Antennas

2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020
We present an actively tuned balun to enable Simultaneous Transmit and Receive (STAR) antennas to achieve greater isolation. Specifically, for the first time, we propose placing an active chip into the balun feed to control the amplitude and phase of the current density.

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

Simultaneous Transmit And Receive with a small planar array

2012 IEEE/MTT-S International Microwave Symposium Digest, 2012
A small three element linear planar array designed to have high isolation between elements for Simultaneous Transmit And Receive (STAR) is demonstrated. This high isolation is achieved through use of tunable resonators that control the near fields of the array without detrimentally affecting the radiated fields.
