Study on Optimum Configuration of Microstrip Bandpass Filters

1998
A hairpin type five-pole Chebyshev filter is designed using method of Wong et al. Frequency responses are simulated with an electromagnetic analysis simulator Sonnet EM. The center frequency, the fractional bandwidth and the ripple of high temperature superconducting (HTS) filter are 5.03GHz, 5% and 0.18dB, respectively.

Microstrip dual‐band bandpass and bandstop filters

Microwave and Optical Technology Letters, 2011
AbstractIn this letter, simple and effective design of dual‐band bandpass and bandstop filters using microstrip open‐loop resonators is proposed.The dual‐band bandpass and bandstop filters developed in this letter exhibit dual operating frequencies that are not integral multiples of each other and are realized using a simple method rather than using ...

A Symmetrical Design of a Microstrip Tunable Bandpass Filter

2020
In this paper an electrically tunable parallel coupled bandpass filter is presented. This type of filter consists of half-wavelength line resonators. The design equations, that are used to find the dimensions of resonators, are given in this paper. Capacitive load is deployed for continuous tuning of center frequency. This paper presents the comparison

Microstrip bandpass filters on substrates with high permittivities

Journal of Communications Technology and Electronics, 2012
A new class of compact microstrip bandpass filters, the stepped-impedance resonators of which are located close together at a gap of 0.1–0.2 mm, is described. Basic two- and three-element sections of microstrip filters, which are designed around stepped-impedance impedance resonators used to implement tiny selective devices with overall sizes and ...

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 ...

Microstrip bandpass filter with high suppression level

12th International Conference Microwave and Telecommunication Technology, 2003
The design of microstrip filter with lumped tapped-inductive couplings is proposed. It is shown that in such a design, due to excluding electromagnetic couplings between resonators, it is possible to increase significantly the attenuation in stop-bands of frequency response. Besides, the use of conductive-inductive couplings allows reducing the overall
