A dual-band bandpass filter using open-loop resonator
Proceedings of 2012 5th Global Symposium on Millimeter-Waves, 2012This paper presents a way of dual-band bandpass microstrip filter design based on open-loop resonator. The asymmetric structure gets better out-of-band rejection comparing to the symmetric structure for the two open-loop ring resonators. This paper also discusses the transmission characteristics of asymmetric two open-loop ring resonators varys with ...

Performance analysis of an open-loop resonator loaded terahertz microstrip antenna
Microelectronics Journal, 2011In this paper, an enhanced electrical performance of the open-loop loaded microstrip patch antenna at terahertz frequency has been investigated. The proposed antenna is designed to radiate at frequencies in the range of 0.5-0.7THz with high gain and radiation efficiency.

A novel microstrip bandpass filter using triangular open-loop resonators
9th Asia-Pacific Conference on Communications (IEEE Cat. No.03EX732), 2004This paper proposes a new four-pole bandpass filter based on the triangular open-loop resonators structure. The full-wave simulator IE3D has been employed for designing the resonators, and calculating the related coupling coefficients of each resonator pair. The proposed filter circuit has been then finally constructed.

Novel dual open-loop ring resonator for compact planar filters
2016 46th European Microwave Conference (EuMC), 2016A novel suspended stripline dual open-loop ring resonator is proposed for the realization of compact bandpass filters. Resonator size below lambda/16 (where lambda is a wavelength in free space) and reasonably high unloaded Q factor can be achieved. First, resonator has been characterized through accurate 3D electromagnetic simulations and suitable ...

ANN based Design of Microstrip Square Open Loop Resonator Filters
2020 Joint International Conference on Digital Arts, Media and Technology with ECTI Northern Section Conference on Electrical, Electronics, Computer and Telecommunications Engineering (ECTI DAMT & NCON), 2020The paper presents a design method for microstrip square open loop resonator filters. This method is based on developing an artificial neural network (ANN) to calculate the spacing between the resonators for given coupling coefficients of the filter, which results in the filter characteristics according to the design requirements. The proposed approach

Improving response of serpentine delay lines using open-loop resonators
2014 22nd Iranian Conference on Electrical Engineering (ICEE), 2014In this paper the utilization of open-loop resonators between traces in microstrip serpentine delay lines is proposed. Grounded guards with vias are conventionally used on serpentine delay line in order to improve signal attenuation. The application of open-loop resonator between serpentine delay line traces improves the signal attenuation in ...

Isolation Enhancement of Patch Antenna Array Using Open Loop Resonator
2018 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2018The paper presents isolation enhancement of 2 element array with rectangular patch antenna. Enhanced isolation is achieved by changing the array configuration and by introducing Open Loop Resonator(OLR) between the patches. The proposed array configuration provides an isolation of 25dB when the individual patches are kept at $\lambda/8$ distance with

The Broadside-coupled Microstrip Structure using Open Loop Resonator DGS
The 2014 International Symposium on Networks, Computers and Communications, 2014A 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, 2011AbstractTo 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), 2019This 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 ...
