抄録	This article presents a topology optimization (TO) of a microstrip bandpass filter (BPF) based on the geometry projection method (GPM) that can represent thin metals and air gaps. A population-based stochastic optimization algorithm is used to optimally place the rectangular air regions in the metal plate of a microwave filter. It is shown that the BPF obtained by the proposed method, which has a thin stub, has the desired characteristic. Furthermore, the better performance of the proposed method over the conventional method is confirmed for the design of the BPF with dual peaks.
