Balanced Diplexer With Widely Separated Differential Passbands Using Input Embedded Resonators
Electronics Letters, Volume 62, Issue 1, January/December 2026.This article presents a balanced‐to‐balanced diplexer using embedded resonators as a common dual‐band input stage, enabling independently tuneable and widely separated differential‐mode passbands without increasing the number of resonators in the output branches.

Adapting Mixer Metamaterials With a Metasurface Absorber
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This study investigates mixer metasurfaces, which use a top frequency‐selective surface (FSS) mixer and a transmission line local oscillator (LO) layer, to optimise the upconversion of signals. Experimental and simulated results detail how input signals (e.g., 2.1–4.45 GHz) on the LO layer switch diodes on the mixer layer, and the structure is ...

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.Enhancing antenna gain remains a key requirement in modern wireless systems, particularly with the rapid evolution of 5G, emerging 6G networks, satellite links, and high‐resolution radar. Recent research trends increasingly rely on frequency‐selective surfaces (FSSs) and metasurface‐based reflectors, which offer precise electromagnetic wave control ...

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.This paper presents a compact dual circularly polarized (CP) stacked‐patch antenna and a corresponding sequentially rotated 4 × 4 array for S‐band satellite communication applications. The driven patch is excited through two orthogonal H‐shaped slots that couple energy from the feedline, while a parasitic patch placed above the driven patch and ...
