Compact bandpass filter with microstrip resonators

2017 18th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM), 2017
This article studies a filter belonging to the category of bandpass filters. This filter has two resonators located on the substrate with dielectric conductivity e=4.4 and thickness h=1.5 mm. Resonators used in the bandpass filter (BPF) allowed for technologically realizable structures with smaller sizes as compared to standard structures.

Miniaturized microstrip bandpass filter with interdigitated fingers

2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013
In this paper, a compact microstrip bandpass filter with improved selectivity and spurious harmonic suppression is presented. The proposed filter design makes use of a resonator with interdigitated fingers to achieve compactness as well as high-selectivity by introducing two transmission zeros, with just two resonators. Miniaturization of about 48% and

Design of cross-coupled microstrip bandpass filter

Physica C: Superconductivity, 2001
Abstract High-temperature superconducting microwave filters were designed for the W-CDMA communication system. Frequency responses of the filters were calculated by the electromagnetic simulator “Sonnet-em”. A cross-coupled 8-pole microstrip line filter shows 1.949 GHz of center frequency and 1.04% of transmission fractional bandwidth on the LaAlO 3 ,

A Microstrip Bandpass Filter Based On Novel Resonators

Journal of Electromagnetic Waves and Applications, 2012
Abstract A microstrip bandpass filter (BPF) using a novel defected ground structure (DGS) resonators and inter-digital capacitors is proposed in this paper. The BPF is designed by cascading a novel microstrip highpass filter (HPF) and a lowpass filter (LPF). The LPF with a 3 dB cutoff frequency of 6GHz is constructed by a laddershaped transmission line

Narrowband Bandpass Microstrip Filter Design

Advanced Materials Research, 2014
This paper analyzes the basic theory of the microstrip narrow-band filter design and accomplishes the design of narrow band-pass filter whose center frequency is on L-band with the help of the Agilent ADS simulation software. The filter adopts Chebyshev’s prototype structure and consists of coupled microstrip line.

Mixed Coupling on Stripline and Microstrip Bandpass Filters

Journal of Communications Technology and Electronics, 2018
The problems of designing stripline and microstrip bandpass filters with mixed coupling, including the magnetic and electric components of the interaction, are considered. It is shown that the transmission zeros corresponding to mixed coupling coefficients can be shifted along the frequency axis by changing the shape of the stepped-impedance resonators.

Bandpass filters using multilayered microstrip structures

2018 Emerging Trends in Electronic Devices and Computational Techniques (EDCT), 2018
The behaviour of the microstrip line structures at the different layers of the substrates, offers an area of research with growing interest. This filter is developed by a conventional three-pole open circuited stub microstrip lowpass filter structure, which shows abrupt change in its behaviour when incorporated with more than one layers of substrates ...

Microstrip based bandpass filters design

2010 20th International Crimean Conference "Microwave & Telecommunication Technology", 2010
The construction principle of modified hairpin bandpass filters in microwave ranges is designed. It is shown, that amplitude-frequency characteristics of the proposed filters have more high steepness decline and best suppression in band of the barrier in comparison with its prototype. These filters are easy in fabrication and adjustment.
