I'm designing a combline filter in ADS using stripline and microstrip. Can someone please tell me why stripline need a 3 layer substrate (MLSUBSTRATE3) and microstrip a 2 layer substrate (MLSUBSTRATE2)?
Stripline is buried inside the dielectric with two ground conductor above and below it. (3 layer substrate)
Microstrip is exposed to air and only have one ground conductor below it. (2 layer substrate)
hello i want to design combline transformer filter with equal diameter round rod plz help me and propose me refrences and plz send them to my email mbanar.kntu@gmail.com
