Hi to all. How can one determine the impedance of a pcb track. The track is about 5cm long , 1.7mm wide , grounded on one end. There is no ground plane.All the searches I've done come up with microstrip calculations which don't seem to cater for this geometry. The track acts as an antenna , so I would like to know it's impedance to design a matching network. This RF stuff is not my strong point , so any pointers would be great. I hope I've given enough info for you boffins out there !!
Cheers Rob
