Hi All,
Im using a PCB loop antenna for near-field communications in the 433MHz ISM band. The antenna is simply a PCB track (35micron x 2mm, 12mm diameter loop) with a short transmission line (track) to it. I have no ground plane extending beyond the transmitter, just the loop itself.
I'm attempting to do some theoretical analysis of the antenna, to see if our results match up with the theory. I have been through a world of literature at this stage and the only theory of PCB loop antennas I have found relates to either microstrip (track above ground plane) or stripline (track between two ground planes). I have also found something on wire loop but this seams unapplicable too.
All i really want is some theoretical values for transmission line Z0 and propagation coefficients, and some impedance value for the loop. Sorry if there is something obvious im missing... im a bit of a nube to RF theory![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
