Filter Design Using Ultra‐Miniaturised Substrate‐Integrated Coaxial Cavity
IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.The proposed substrate‐integrated coaxial cavity (SICC) comprises two dielectric substrates with three metal layers. The top and bottom metal layers form the cavity's broadside walls, and the middle is a circular patch that shorts to the bottom wall and to an embedded split CPW ring, respectively, through a blind‐via ring and three blind vias.

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.In this paper, a hybrid coding method for chipless radio‐frequency identification (RFID) tag with angular orientation is proposed. Frequency‐shift coding is achieved by controlling the size of three complementary split single ring resonators (CSSRR). And on the basis, we add a dimension of polarisation coding, which is achieved through changes in the ...

A Novel Coupling Mechanism for CSRRs as Near-Field Dielectric Sensors
Sensors, 2022 This work proposes a novel coupling mechanism for a complementary split-ring resonator as a planar near-field microwave sensor for dielectric materials. The resonator is etched into the ground plane of a microstrip line. This mechanism is based on the inductive coupling synthesized by utilizing a via that connects the power plane of the microstrip line
