碩士 === 國立屏東科技大學 === 機械工程系所 === 101 === A novel dual-band bandpass filter using patch resonator for WiMAX system is designed and implemented. The response of first and second band can be controlled according to adjust the length of slit on the resonator. To enhance coupling capability by feed lines in input/output port. Furthermore, the transmission zeros can be produced to increase the selectivity of passband. The frequency of the dual-band bandpass filter is 2.12/3.19 GHz. And the operating frequency is controlled by adjusting the peripheral length. The measured results of the designed dual-band bandpass filter using patch resonator confirm the concepts of the proposed design and match the simulated results.
