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 ...

Synthesis of multi‐band filters based on multi‐prototype transformation
IET Microwaves, Antennas & Propagation, 2021 In this article, a new synthesis method for generalized multi‐band filters has been proposed. Different from the traditional frequency transformation method, which transforms a low‐pass prototype into a multi‐band filter, multiple low‐pass prototypes ...

Efficient reconstruction of band-limited sequences from nonuniformly decimated versions by use of polyphase filter banks [PDF]
, 1990 An efficient polyphase structure for the reconstruction of a band-limited sequence from a nonuniformly decimated version is developed. Theoretically, the reconstruction involves the implementation of a bank of multilevel filters, and it is shown that how

On the Designing of Spikes Band-Pass Filters for FPGA [PDF]
, 2011 In this paper we present two implementations of spike-based bandpass filters, which are able to reject out-of-band frequency components in the spike domain. First one is based on the use of previously designed spike-based low-pass filters.

Design of a Compact Balanced Tri-band Bandpass Filter Using Simple Planar Resonator with Wide Stop-band and High Selectivity [PDF]
AUT Journal of Modeling and Simulation, 2021 The most balanced multiband band-pass-filters have some remarkable properties while provide a trade-off between design goals. Additionally, few of them have provided a structure capable of satisfactory harmonic suppression.
