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?
How to improve the return loss perfomance?
Please help me to
solve this problem.
