Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all

Post subject: Microstrip Bandpass filter Posted: Mon Jul

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.
