چکیده
Abstract In this article, a compact microstrip lowpass filter (LPF) using elliptical shaped resonators with ultra-wide stopband is rendered. respect, LC equal structures of the are calculated based on formula circumference. addition, to calculate transmission zeros presented resonator, structure and its output input ratio employed. The proposed LPF has −3 dB cut-off frequency at 1.50 GHz bandwidth designed about 13 f c, which refers stopband. occupied circuit size 0.151 λ g × 0.044 ( guided wavelength GHz). fabricated RT/Duroid 5880 substrate. results have clearly demonstrated that not only shown suitable agreement between measured simulated S -parameters, but also an appropriate bandwidth.

Compact Microstrip Lowpass Filter with Sharp Roll-off and Wide Stopband Using Semicircle Ended Stub Resonator
In this paper, a semicircle ended stub resonator, cascaded to a modified radial patch to design a compact lowpass filter with sharp roll-off and wide stopband is proposed. This filter has 3 dB cutoff frequency at 1.54 GHz. The transition band is only 0.26GHz from 1.54 GHz to 1.8 GHz with corresponding attenuation levels of −3 dB and −20 dB respectively. Maximum insertion loss is 0.1 dB in the p...

A novel elliptical patch resonator for a compact bandpass filter with tunable bandwidth is presented. This bandpass filter has the advantage of great flexibility in which the center frequency can be changed easily. The bandwidth of this filter can be modified by simply changing one variable, and this makes the proposed design unique. The order of the elliptical patch resonator can be increased,...
متن کاملCompact Microstrip Lowpass Filter with Wide Stopband and High Attenuation
A compact microstrip lowpass filter using radial stub resonators is developed. This filter is composed of two radial stub resonators that are asymmetrically connected to each other by a stepped impedance structure. This structure results in a very high rejection and wide stopband. The proposed filter with a 3 dB cutoff frequency of 2.07 GHz has been designed, fabricated and measured. Measuremen...
