The Broadside-coupled Microstrip Structure using Open Loop Resonator DGS

The 2014 International Symposium on Networks, Computers and Communications, 2014
A novel design method of an ultra wideband (UWB) microstrip bandpass filter (BPF) based on The Broadside-coupled Microstrip and Open Loop Resonator defected ground structure (DGS) is presented. This filter provides in the passband an insertion loss of 0.3 dB and a return loss greater than 22 dB. In addition, the filter is compact size of 9.39×4.29mm 2

Miniature bandpass filter with wide stopband using open‐loop resonators

Microwave and Optical Technology Letters, 2011
AbstractTo reduce the size and improve the performance, a miniature microstrip bandpass filter (BPF) is investigated in this article. On the basis of open‐loops, an interdigital capacitive load has been connected. The new design has advantages of a compact size and a large ratio of the first spurious resonant frequency to the fundamental frequency.

Millimeter-Wave Bandpass Filter By Open Loop Elliptical Ring Resonators

2019 International Conference on Electrical Engineering and Computer Science (ICECOS), 2019
This paper presents a bandpass filter using two elliptical open loop ring resonators(EOLRR) at the resonant frequency of 28 GHz. It is well suited for the next generation 5G application. Coupled resonators were developed with the expectation of pairing parasitic resonance of various degenerate modes operating close to the fundamental mode in the ...

The design of open-loop resonator HTSC linear-phase filter

Cryogenics, 2007
The coupling gap between traditional open-loop microstrip resonators of high temperature superconductivity (HTSC) filter is too narrow to be fabricated with normal photolithography technology. The mixed couplings of HTSC open-loop microstrip resonators are studied in this paper and a new improved resonator structure that can be fabricated with normal ...

A novel bandpass filter with dual-mode open-loop resonators

2017 7th IEEE International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE), 2017
In this paper, we propose a novel microstrip bandpass filter (BPF) based on dual-mode open-loop resonators (DMOLRs). The proposed bandpass filter consists of two coupled DMOLRs, which can be treated as the combination of a folded T-shape stub and a W-shape stub.
