Hi all,
I am trying to design a Microstrip
bandpass filter using edge Coupled Tapped line structure. After designing
and simulating it in ADS, i found variations in the actual performance
and simulation result. I found that there is a shift in the band and
poor return loss.
Can anyone please suggest me
1.why i am
getting shift in the band??
2. Why there is mismatch in the simulation
and actual response even though i am feeding the substrate information
in the simulation?
3. How to control this shift in the band?
4.
How to improve the return loss perfomance?
Please help me to
solve this problem.
