Performance Analysis of Stripline Bandpass Filter With Tunable Structure

Shubha Gupta; Kanchan Cecil

Band pass filters play a significant role in wireless communication systems. Transmitted and received signals have to be filtered at a certain center frequency with a specific bandwidth In this paper, tunable narrow band pass filter (BPF) development with the assistance of the Richards-Kuroda Transformation method, on the basis of the known Chebyshev – Low pass Filter, is presented. This suggested filter consists of four edge-coupled strip lines. The performance is compared with other fixed band stripline filters {&} other tunable filters. The filter is operated at upper L-band frequency segment of 1.3 GHz to 1.5 GHz for satellite application. The proposed circuit is simulated using MATLAB software {&} Roger substrate with dielectric constant of 3.55, substrate height of 0.8 mm. This improves the performance greatly to achieve the maximum possible Q within the pass band. The simulation results are good enough {&} show smooth tuning. The filter is suitable for integration within various microwave subsystems.
