Abstract: The present paper represents the design and simulation of multiband band pass filter using the hairpin resonator. Two rectangular slot defects are made in the ground plane. The filter is designed on a substrate having thickness of 0.3mm. The filter exhibits improved performance and good selectivity. The filter shows good return loss at 5.0 GHz, 5.7 GHz, 6.5GHz, The return loss of the simulated filtered are measured as -18dB, -16dB, -23db, while the insertion loss are -0.05dB, -0.08dB, 0.1dB. The present work will also be suitable for multiband and multiservice applications.
