Abstract

Hairpin resonator is an essential component in Radio Frequency (RF) communication systems. In this paper, a microstrip hairpin resonator is designed using the Advanced Design System (ADS). The hairpin resonator is optimized to operate at a center frequency of 5.8GHz and matched with 50Ohm impedance. The simulation results show that the designed hairpin resonator has an insertion loss of 20dB and a return loss of 1.6dB at the center frequency. The Q factor of the designed resonator is 22.8, indicating good performance. This resonator can be applied to 5.8GHz communication system applications. The proposed design provides a low-cost and small size as well.
