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 ...

Magnetostatic waves in the gap between two ferromagnetic with longitudinal magnetizations that move relative to each other

Физика волновых процессов и радиотехнические системы, 2013
The propagation of a magnetostatic gap wave in a gap between two ferromagnetic with opposite longitudinal magnetizations is considered under the conditions for relative longitudinal displacement.

A High‐Precision Triboelectric Rotational Sensor for Enhanced Low‐Speed Monitoring via Magnetic Modulation in Smart Fitness Systems

SmartSys, Volume 1, Issue 4, December 2025.
ABSTRACT Real‐time detection of low‐speed motion and precise monitoring of low‐intensity exercise are crucial for smart fitness systems. These capabilities enable continuous data acquisition, capture subtle motion variations for personalized guidance, and enhance training effectiveness while reducing the risk of injury. However, conventional rotational

Perpendicularly magnetized YIG-film resonators and waveguides with high operating power

AIP Advances, 2017
We propose a novel technique for building YIG film-based resonators and waveguides for high power operating microwave devices. Our approach is based on the effect of total internal reflection (TIR) at the interface between the non-metalized and metalized

Active narrowband magnetostatic wave filter

Electronics Letters, 1999
An active passband microwave filter consisting of a magnetostatic wave (MSW) delay line and microwave amplifier has been developed and tested. A narrow passband of 120 kHz was obtained at the S/C-band corresponding to a quality factor Q of ~40000. The frequency response characteristics are presented.
