Parallel Coupled Microstrip Band-pass Filter Design for C-Band TV Satellites

In this paper, a microstrip parallel coupled-line band-pass filter, which is based on the 7th order Chebyshev filter response, is designed to operate at the center frequency of 4.1 GHz for downlinks of C Band TV Satellites for the first time in the existing literature. The electrical performance of the proposed band-pass filter is numerically evaluated by using AWR Microwave Office in the frequency range of interest. Moreover, the electric and magnetic field distributions of the filter are obtained at the center frequency using 3D full-wave electromagnetic simulation software CST Studio. Finally, the simulation results are experimentally verified in terms of S-parameters.
