Abstract

In this paper, synthesis of bandpass filter is performed by using coupling matrix based method. To design a bandpass filter, the standard lowpass to bandpass frequency transformation has been used. Bandpass filter is implemented by using coupled microstrip resonators with both electric and magnetic coupling. The frequency transformation is performed and verified in MATLAB. The layout of filter obtained from coupling matrix is further reduced in size by using some topologies of filter designing. The proposed filter is designed and simulated in ANSYS HFSS software and RT_Duroid is used as dielectric material with substrate thickness of 1.27 mm. The filter response is found in good agreement with the response found from the mathematical model.
