چکیده
Abstract— In this paper a high performance Bandpass micro strip filter is presented. The filter is designed using interdigital bandpass filter to improve the performance of Bandpass filter. The designed filter is based on 5th order chebyshev low pass prototype with .1 dB passband ripples. The filter operates with passband from 2GHz-4 GHz, produces a fractional bandwidth of 66%. The filter is designed on a FR4 substrate with relative dielectric constant of 4.4 and a thickness of 1.57mm. The simulated result using HFSS shows an insertion loss (S21) less than -1.8dB and return loss (S11) better than -8 dB.

A Compact UWB Bandpass Filter with High Selectivity and Dual Notched-Band
A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...

A novel high temperature superconducting interdigital bandpass filter is proposed by using coplanar waveguide quarterwavelength resonators. The CPW resonators are arranged in parallel, and consequently the filter becomes very compact. The filter is a 5-pole Chebyshev BPF with a midband frequency of 5.0 GHz and an equal-ripple fractional bandwidth of 3.2%. It is fabricated using a YBCO film depo...

In this pare, a wideband three-order bandpass filter (BPF) is proposed. The proposed wideband filter is designed using the substrate integrated waveguide (SIW) structure by loading T-shape slots. A BPF with two resonators is formed by etching T-shape slots with different size on the top metal plane of the SIW structure. The filter is investigated with the theory of coupled resonator circuits. T...

In this paper, a compact ultra-wideband bandpass filter (UWB-BPF) using pseudo-interdigital stepped-impedance resonators (PIDT-SIRs) is designed and implemented on a commercial printed circuit board (PCB) of RT/Duroid 5880 substrate. The first two resonant modes of the SIR are coupled together and they are applied to create a wide passband. The proposed filter at center frequency f0 of 7.1 GHz ...
