Direct design method for wideband quadruplet and higher‐order bandpass filters with a pair of transmission zeros based on explicit design formulas

IET Microwaves, Antennas & Propagation
This paper presents a direct design approach and explicit design formulas for a wideband quadruplet bandpass filter with a pair of transmission zeros. A filter can be designed based on a filter schematic composed of only transmission lines and a short ...

Design of Compact BPF and Planar Diplexer for UMTS using Embedded-scheme Resonator [PDF]

, 2013
A compact planar diplexer utilizing embedded-scheme resonator (ESR) is designed for universal mobile telecommunications system (UMTS). The ESR is formed by embedding interdigital resonators into an open loop resonator.

Novel microstrip bandstop filter

Electronics Letters, 1977
A microstrip bandstop filter is described that overcomes the problems of radiation and surface-wave generation at high frequencies (40 GHz). An attenuation greater than 17 dB has been measured over at least a 10% bandwidth. The peak attenuation in the band can exceed 30 dB.
