摘要：

This paper presents a topology optimization of a microstrip bandpass filter based on the geometry projection method 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 bandpass filter obtained by the proposed method, which has a thin stub, has a desired characteristic.
