Wideband Band-pass Filter With Defected Ground Structure

摘要：

　　A new type of wideband band-pass filter based on DGS structure is investigated with simulation in this paper.The filter is based on the SIW structure.In order to obtain advantages of compact structure and good performance,DGS and defected microstrip structure are adopted.The filter has the advantages of small size and easy integration.CST Microwave studio software is used to simulate the proposed filter.From the simulation results,the filter center frequency is 16.4GHz,fractional bandwidth is 68.3%,and the return loss is less than-10dB.
