A monostatic dual-polarized simultaneous transmit and receive (STAR) antenna system with
high isolation is introduced. A beamforming network (BFN) producing 0°,±90°,±180° …

Broadband copolarized monostatic circular-antenna arrays based on mode orthogonality
principles are presented for in-band full-duplex (FD) applications. The simultaneous …

Wireless technology is growing at a fast rate to accommodate the expanding user demands.
Currently, the radio frequency (RF) spectrum is overcrowded. Hence, it is more susceptible …

A multimode lens-loaded eight-arm spiral aperture is proposed for in-band full-duplex
applications. Specifically, the single eightarm spiral antenna is composed of a four-arm …

A true in-band full-duplex (IBFD) co-circularly polarized (CP) Van Atta array with the active
enhancement of the radar cross section (RCS) at 2.45 GHz is demonstrated for the first time …

This paper presents the design of dual-port subarray modularization integrating a three-port
circulator, realized by using substrate integrated waveguide (SIW) technology, and a …

This article introduces an ultra-wideband (UWB) shifted arc antenna, designed using Rogers
RT-5880 Duroid substrate for the human detection behind the wall. The frequency for this …

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 …

Most modern wireless communication systems operate either at different times or
frequencies to avoid self-interferences. With these duplexing techniques, more resources …

Several novel wideband co-polarized circulator-less monostatic antenna and array designs
for co-channel simultaneous transmit and receive (STAR) applications are presented. The …
