Feed point problem! Please help...

Hi there,

I'm now doing analysis rectangular patch antenna. And using microstrip line feed for feeding. There are 3 types for this feeding.
1) nonradiating edge (end-edge)
2) radiating edge with inset-fed
3) radiating edge with quater-wave transformer

May anyone tell me that is it the feed point for 1 and 2 is same? I mean using the same equation [ yo = L/pi cos √( Zin/Rin0) ] to calculate the feed point.

Thanks in advance.
