My tool for designing elliptic stripline filters


Nico Coesel

Jan 1, 1970
A couple of months ago I posted a question on how to design an
elliptic filter made out of micro stripline. That got me some pointers
but not a clear answer. After some more Googling I found a book which
had a couple of equations. Those are so difficult to solve I couldn't
get away with an Excel sheet let alone solve them by hand. So decided
to write my own solver. Being at it I wrapped it into a nice GUI and I
decided to turn it into a (cheap) product.

Ofcourse I did some simulation and testing and it turns out the
geometries calculated by my program produce working filters!

It available for download from my website:

At this moment it can only calculate geometries of 3rd, 5th and 7th
order elliptic filters (which is by far the hardest part).
