There is a paper of Fano on Wideband Circuit matching..but it is very mathematical one...and also...I think it is not IEEE paper..but u can search under UWB case for windeband matching...it is same..UWB Antenna matching...
Hi Balaguru,
Acatully original paper written by Fano is not avaliable anywhere online.(If anyone has it pls upload it) and the reason people don't refer to it coz it is very mathematical one.I got to see it in our library sometimes back but now it is not there.
Here I am uploadingthree papers which are related to to topic and hope you will find it helpful.
This Fano case study is widely used as limit case and can be seen in UWB antenna topics.
If you have UWB Antenna books you can check it for the same.
