Wideband bandpass filters with suppressed harmonics using vertically installed planar structures
IET Microwaves, Antennas & Propagation, 2023 This article presents a closed‐form synthesis method for wideband bandpass filters with suppressed harmonics, where stepped‐impedance resonators (SIRs), scaled lines, and vertically installed planar (VIP) structures are introduced to improve the in‐band ...

Direct Calculation of Band-Pass Filters
Известия высших учебных заведений России: Радиоэлектроника, 2022 Introduction. When calculating band-pass filters (BPF), the circuit elements can be determined by converting the parameters of prototype low-pass filters (LPF).

IET Signal Processing, 2022 Maximally flat digital differentiators (MFDDs) are very attractive for differentiation of narrowband signals. The design of infinite impulse response (IIR) MFDDs, however, is very challenging due to the non‐convexity of the flatness constraints of the ...

A THz Spectrometer Using Band Pass Filters
Instruments, 2020 We describe a THz spectrometer operating between 1.2 and 10.5 THz, consisting of band pass filters made by metasurfaces. The source is made of a 10 W small black body. The detector is a high sensitivity room temperature pyroelectric sensor.

Fractal and Fractional, 2022 This paper proposes a further generalization of the fractional-order filters whose limiting form is that of the second-order filter. This new filter class can also be regarded as a superset of the recently reported power-law filters.

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 ...

Filter function synthesis by Gegenbauer generating function [PDF]
Serbian Journal of Electrical Engineering, 2006 Low-pass all-pole transfer functions with non-monotonic amplitude characteristic in the pass-band and at least (n -1) flatness conditions for ω = 0 are considered in this paper.
