Hi all
i'm going to design an infinitesimal electric dipole above an infinite pec for height lambda/2.I'm going to earn figure 4.17 in antenna book,Balanis but the results aren't good at all.(VSWR and radiation pattern)
i don't know how length i need for air gap in infinitesimal dipole?and don't know what is the problem?
I'm using HFSS13
and dimensions:
height from pec=lambda/2
thanks in advance
