TL;DR: In this paper, a planar microwave ring resonator operating at 5.25 GHz with a quality factor of 224 was constructed to measure the resonance frequency and Q-factor of the microwave resonator with the sample to be probed placed in a defined sensitive region of the resonator where the microwave field is highly concentrated.

TL;DR: In this article, a new model for further reducing the size and increasing the bandwidth of a class of bandpass filter (BPF) utilizing multi-mode resonator is presented, and a new technique based on spiral transmission line loading to achieve higher BW and further size reduction is analyzed for this class of BPF.

TL;DR: In this article, a new coupling structure was proposed to demonstrate a constant coupling strength for longer distances in planar microwave sensors, where the authors showed that there is a positive correlation between the gap size in a pair of gap-coupled transmission lines (GCTLs) and the effective distance of reader and sensing resonators.

TL;DR: In this article, a noninvasive contactless binary gas sensing system is enabled using coupled passive flexible tag integrated with porous adsorbent beads tower, which demonstrates the capability of detecting and monitoring more than one gas simultaneously and independently from each other.

TL;DR: In this article, the L-shaped iris (LSI) embedded in substrate integrated waveguide (SIW) structures was investigated to thoroughly discuss the iris behavior in a wide frequency band.
