Circuit‐Theoretic Modeling and Simulation Study of Near‐Field MIMO Arrays of Dipole Antennas
Active and Passive Electronic Components, Volume 2026, Issue 1, 2026.Near‐field mutual coupling among closely spaced antennas limits the deployment of wireless MIMO interconnects in chip‐to‐chip communication. This paper presents a circuit‐theoretic modeling and simulation study of near‐field MIMO (NFMIMO) systems using 1 × 1 and 2 × 2 dipole arrays.

Nested Horn‐Based 3D‐Printed Dual‐Band High‐Gain Conical Beam Antenna
IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.The proposed antenna is committed to simultaneously possess dual‐band, high‐gain, wideband and conical beam performances. The design of the nested horn and the impedance change caused by the ridge waveguide can provide a simple and easy‐to‐implement idea for dual‐band wideband antenna design. Meanwhile, the loading of dual reflectors not only increases

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.In this paper, we propose a three‐dimensional integral equation‐based GSTC solver for the electromagnetic analysis of metasurface composite structures. We present a novel numerical method, focusing on the rigorous enforcement of boundary conditions at the interfaces, a critical aspect in the problem formulation for composite structures.

A Flexible K‐Band FMCW Radar Prototype for Low‐RCS Nano‐Drone Detection
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.A 5‐cm nano drone with its Doppler signature. ABSTRACT Nano‐drones are insect‐like drones used to provide intelligence through their capability of intrusion and ability to carry small sensors. They pose a defence and security threat and can potentially violate secure establishments and privacy rights.
