Hi,
Do you guys have any paper about this kind of taper balun?
I am interested in it.
Thx in advance.

I would also love to see a paper on how to design the balun.

The attaced files are some papers about Microstrip tapered Balun.

I'm looking for papers about baluns as well. IEEE explorer have lots of them. I have a few things, If you need something concret please ask me

Sorry for two messages. I'm using HFSS for simulating broadband baluns. Any idea of where may I find some more info?
