Design and Optimization of Microstrip Stub Bandstop Filter Based on ADS

Abstract:

Microstrip filter has extensive application in microwave circuit and communication system in the future. We take lumped components low-pass filter as the prototype and employ the Richards transformation and the Kuroda rule to change the low pass prototype into a bandstop filter. By using ADS (Advanced Design System) method we design a microstrip stub bandstop filter, whose center frequency, range of frequency and relative width are respectively 4GHz, 3GHz ~ 5GHz and 8%. And then we further optimize the parameters to get the circuit design layout. It is shown that all indexes reach the design requirements and the method possesses the features such as short period and high reliability.
