Miniaturised single‐layer bandpass filters using triple and quad‐mode patch resonators

open access: yesIET Microwaves, Antennas & Propagation, 2023
The authors propose miniaturised single‐layer bandpass filters (BPFs) by utilising a kind of new triple‐ and quad‐mode patch resonators. The triple‐mode resonator consists of a shortened square patch and a loaded metallic via at the centre ...
