Additive Manufacturing of Broadband Dielectric Resonator Antennas Using Graded Permittivity and Modal Analysis

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This study enhances the bandwidth of dielectric resonator antennas (DRAs) by introducing a linearly graded permittivity profile. Characteristic Mode Analysis reveals that this approach broadens the modal distribution and extends the dominant resonant mode bandwidth.

Wideband and Frequency‐Reconfigurable Loop Antenna for Sub‐6 GHz Applications

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
This work tackles the longstanding bandwidth limitation of loop antennas by introducing a compact, symmetrical design that integrates a microstrip balun and periodic varactor loading. Unlike existing methods that often compromise symmetry or beam control, the proposed structure achieves both wide impedance bandwidth and frequency reconfigurability ...
