Multi‐band glass‐integrated bandpass filters for new radio (NR) communications
Electronics Letters, 2023 A class of multi‐band bandpass filters (BPFs) based on glass‐integrated multi‐resonant cells (MRCs) are reported. Each MRC comprises multiple in‐parallel connected series‐type resonators that create passbands in‐between transmission zeros (TZs)—located ...

Optimization of Butterworth and Bessel Filter Parameters with Improved Tree-Seed Algorithm
Biomimetics, 2023 Filters are electrical circuits or networks that filter out unwanted signals. In these circuits, signals are permeable in a certain frequency range. Attenuation occurs in signals outside this frequency range.

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

Parametrically enhanced bandpass filters
IET Microwaves, Antennas & Propagation, 2021 This paper proposes a technique to enhance the quality factor (Q) of a resonator, which can then be used to realise bandpass filters (BPFs) with reduced insertion loss (IL) and improved passband selectivity.
