Abstract: A new practical design for hairpin resonator filters is presented in this study. The typical hairpin filter has been optimized by changing the resonators and the gap between resonators. The preferences in bandwidth return loss and insertion loss has been improved. The proposed filter simulated using the commercially available simulation software Ansoft HFSS and fabricated that is verified by good agreement between simulated and measured results. Measurement results show <1 dB insertion loss and return loss better than 8 dB.
