In this paper, we propose a hexagonal microstrip dual - mode band pass filter by optimizing various geometrical parameters associated with the filter geometry using IE3D full-wave simulation software. The response of the optimized filter is studied and analyzed and the results have been reported. Work also explores the possibility of changing the type of the filter response from Elliptical to Chebyshev...
In this paper, a quasi-elliptic bandpass filter was designed, simulated, and fabricated using four-pole cross-coupled stepped impedance resonators (SIR). Using a special type of stepped impedance resonators, a great increase in rejection band width of the filter was obtained. In order to perform the mentioned design practically, we utilized a compound sandwich model of two substrates (in strip line...
A synthesizing method is presented to design elliptic band-pass filters in the microwave frequency range. The elliptic band-pass filter is implemented by using a coupled-serial-shunted line structure. Using a continuous perturbation of wiggly-groove and ring resonator of the couple line the harmonic pass-band of the filter is rejected. An elliptic band-pass filter is implemented to validate this method...
This paper introduces a microstrip triple-mode resonator that is realized by adding an additional path to an already reported microstrip square-loop dual-mode resonator. The additional path is realized by a meander half wavelength strip that is connected to two opposite corners of the square-loop resonator. A third order pseudo-elliptic bandpass filter utilizing this resonator is presented. Good agreement...
