## Abstract A mixed coupling structure is proposed for the cross coupling of a comb‐line filter. The proposed structure consists of an electric coupling probe and a magnetic coupling window, and the coupling required for the cross coupling of a cross‐coupled filter can be achieved with much easier

Abstract
This article proposes a method of double cross‐coupling lines to produce the transmission zeros independently in the both close‐to‐band rejections of HTS filter, and that their positions are controllable. An eight‐pole HTS filter is simulated to present the feasibility of this method. According to this method, a four‐pole HTS filter has been designed and fabricated. The experimental results have good agreement with simulation and support this method. © 2008 Wiley Periodicals, Inc.

## Abstract This paper discusses various changes made in classical coupled‐line narrow bandpass filters to somehow improve frequency response. First, the resonator's strip width was broadened to improve the lines' unloaded __Q__ factor. Second, the in/out coupled‐line sections were replaced by tapp

## Abstract This article presents the design of a compact fourth‐order cross‐coupled dual‐band bandpass filter (BPF) having a wide upper‐end stopband. Quarter‐wavelength (__λ__/4) stepped‐impedance resonators (SIRs) were employed to construct the BPF to have a relatively small circuit size and high
