Abstract
This paper deals with the study of ultra-wideband (UWB) microstrip bandpass filter (BPF) using four strip elements with defected ground structure (DGS) incorporation. Here, the DGS is applied for enhancing the passband bandwidth response, S-parameters, as well as for size miniaturization. In the design process, some parametric studies of DGS such as changing the length of DGS, width of DGS, and number of DGS slot are performed to optimize the microstrip BPF in achieving the optimum bandwidth response and S-parameters. Microstrip BPF is deployed on a 0.8mm thick FR4 epoxy dielectric substrate with the dimension of 27.4mm × 22mm. The simulation result shows that the proposed microstrip BPF has bandwidth response of 4.55GHz ranges from the frequency of 1.4GHz to 5.95GHz.
