An ultra‐wide stopband microstrip bandpass filter

Microwave and Optical Technology Letters, 2010
AbstractThis article develops a novel microstrip bandpass filter with ultra‐wide stopband.With the assistance of open stubs and interdigital capacitors, a very wide stopband with a sufficient rejection level can be achieved easily. Detailed design and synthesis procedures are provided. Moreover, the electromagnetic simulator ansoft designer v3 is used,

Broadband microstrip antenna with a hairpin bandpass filter

Technical Physics Letters, 2015
A new design for a broadband microstrip antenna is proposed, the working band of which is broadened using a bandpass filter based on two hairpin resonators electromagnetically coupled with a half-wave radiating resonator with a rectangular strip conductor.

MICROSTRIP BANDPASS FILTERS PROTOTYPING IN THE LABORATORY CONDITIONS

ВЕСТНИК ВОРОНЕЖСКОГО ГОСУДАРСТВЕННОГО ТЕХНИЧЕСКОГО УНИВЕРСИТЕТА, 2023
при проектировании устройств диапазонов ультравысоких (УВЧ) и сверхвысоких частот (СВЧ) зачастую необходимо иметь возможность оперативно уточнять результаты расчетов. Такую возможность может предоставить макетирование в лабораторных условиях. Важным вопросом при этом является степень соответствия расчетных параметров параметрам полученного макета, что ...

Hybrid microstrip compact hairpin bandpass filter

2009 Asia Pacific Microwave Conference, 2009
A four-pole elliptic function band-pass filter is designed using miniaturized microstrip inter-digital hairpin resonator and step-impedance hairpin resonator. Miniaturization hairpin resonators are realized by using inter-digital structure and step-impedance structure having parallel coupled lines.

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

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.

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

The microstrip bandpass filters with wide outband suppression

2006 Asia-Pacific Microwave Conference, 2006
The newly H-type microstrip bandpass filter is proposed in this paper. The use of H-type resonators not only can lead the second passband to the higher frequency band, but also can attenuate the shifted second passband to increase the suppression and broaden the stopband. The design methods and the measurements of the fabricated examples are introduced

Compact triple-mode microstrip bandpass filter

2012 IEEE 14th Electronics Packaging Technology Conference (EPTC), 2012
In this paper, a novel I/O stage coupling scheme is presented for exploration of a microstrip triple-mode bandpass filter with improved out-of-band rejection performance. Firstly, a modified microstrip triple-mode stub-loaded resonator is formed by tap-connecting a λ/2 microstrip line resonator with a pair of open-circuited stubs of less than λ/4 in ...
