Can a Patch Antenna be modeled in EZNEC?
Do you make the flat plates with parrallel lines?

patches are tough to do a *good* job on with a MoM wire type code (such
as NEC, EZNEC, etc.).

A good start is to make a grid of wires, say, 21x21 wires, with the wire
diameter chosen so that the surface area is comparable to the gap (that
is, if the wires are d cm apart, the wire diameter would be d/pi cm.

Obviously, this breaks down horribly if your microstrip is spaced very
close to the ground plane and you use few wires.


You could also download Pozar's free microstrip patch program. PCAAD 2.1
from http://www.antennadesignassociates.com/
Old, DOS style, but works


Or is there a function to give you a solid plate?
