| Summary: | The novel Reconfigurable Dual-Band Bandpass Filter with Capacitive Elements Insertion is presented. This filter design is applicable for L band military radar application. These paper proposed of designing a microstrip reconfigurable dual-band bandpass filter based on an existing dual-band bandpass filter topology using High Frequency Structural Simulator (HFSS). This basic filter topology involve couple-line with transmission line forming a dual-path that produce a dual-band frequency response. The center frequency of this filter design was stated at 2 GHz. Overall, the basic dual-band bandpass filter operated at center frequency 1.35 GHz and 2.71 GHz. A pair of additional lumped capacitor converted into distributed element is added at suitable location on the basic design in order to shift the frequency response. The center frequency of this filter design was shifted from 2 GHz to 1.73 GHz by varied capacitance value in order to reconfigure the frequency response. |
