Hi Robert,
SPICE is a time domain tool, you might have difficulty finding a suitable
model as most antenna analysis is performed in the frequency domain. To find
the radiation resitance and impedance of a monopole is easy using one of the
NEC family of codes (Numerical Electromagnetics Code) MininNEC etc. but this
would not be a sufficient model for a SPICE run.
Length diameter, feedpoint etc can all be considered but I know of no efficent
tool for doing this in the time domain.

Subject: PSpice model for 1/4 wavelength antenna
Does someone out there have a PSpice model for a 1/4
wavelength antenna? 433.92MHz
Something that I can change to reflect diameter of the rod,
detuning, etc.
Or, do you know someone who has such a model?
Need it fast, please.
