This paper presents a new type microstrip hairpin dual-bandpass filter, and gives out design principle for the filter and its structure, analyzes and compares the effects of different structural parameters on the filter characteristics. Its characteristic curve chart is concluded by simulation and optimization. And the results show that the designed microstrip dual-bandpass filter has perfect bandpass characteristic, and the dual-bandpass of 2.4GHz/5.2GHz and 2.4GHz/5.8GHz is realized. In addition, the designed filter is in small size. Therefore, the miniaturization of the system is easily implemented.
