FIVE POLE OPTIMUM DISTRIBUTED HIGH PASS MICROWAVE FILTER: DESIGN ANALYSIS AND SIMULATION ON MICROSTRIP AT 2.4 GHZ

This paper presents a frequency responsive design of an optimum distributed high pass filter having a cutoff frequency fc = 2.4 GHz and a 0.1 dB ripple passband up to 10.4 GHz with Z0 = 50 ohm. This presents a novel design of Chebyshev HPF prototype with substrate thickness 1.6 mm, strip thickness 0.035 mm, FR4 substrate relative permittivity is 4.4 and dielectric loss tangent 0.02. The simulated results for the filter are in good concurrence. The analysis of the High pass planar filter is performed using the Ansoft’s HFSS simulator. Snapshots of the simulation and the graphical results obtained are shown in the paper.
