In this paper, the authors present the design of five pole microstrip bandpass filters with hairpin and combine configurations with a center frequency of 4.8GHz. The simulation is performed using ADS simulation tool. The filters are designed for different substrates like FR4, RT/Duroid 6010, and RO3010. The filter performance is compared for these substrates in terms of insertion loss and return loss. The simulated results show that both filters are operating well for the desired specifications and the substrate with higher dielectric constant provides higher return loss and lower insertion loss for both filter configurations.
