    what is fullwave analysis ???

    is this sentence right in general? Full wave analysis means: "exact analitical (not numerical) solution without any approximation" for example, when we solve an aperture antenna approximately by means of infinite ground concept we don't make a fullwave soloution...??? by the way, is there any...

    How should i feed this antenna [60 point award]

    Re: How should i feed this antenna [50 point award] hi marshal, if your structure doesn't have ground plane you could supply it easily by lumped gap port but now it is realy hard. i realy don't know how are you able to feed this antenna by hfss when it has ground plane!!!!????
