Microstrip Hairpin Bandpass Filter

S-Parameter EM/Circuit Co-Simulations

 

 

 

General Description

 

S-parameters are calculated and optimized for a bandpass filter in microstrip. You will find two projects: an initial design and an optimized one.

 

Model Description

 

The microstrip coupled lines two-port blocks realize the coupling of four resonators each producing one pole that cause the filter characteristic of the system. Note that substrate properties are defined by using a reference block (marked by a black arrow).

 

To optimize the initial design five parameters are included into the optimization process that uses the genetic algorithm.
