edge currents of patch antenna
Hi!
I tried to simulate a patch antenna using FDTD. This patch is fed by a microstrip line.
In general it is working fine. but there is one unwanted effect: the currents flowing along the resonant length on the patch are not of the same size along the width of the patch. there is a strong and sudden increase towards the edges. the width of the patch or the frequency have no influence on this increase.
Does anybody know what might be the problem?
Thanks for your help
