Antenna, electromagnetics and transmission line simulators are a special breed of
software because of the sophisticated 3-dimensional electromagnetic equations that must
be applied. Designing antennas for first-pass success requires a very high level of sophistication
by the software. It must contain component models (including substrates and enclosures)
that accurately compute values that take into account the many parasitic effects of lead
inductance, interwinding capacitance, resistance of the component, etc. Generally, price
correlates directly to the capability of the software. At the top of the list is software
that is free and/or offers free trial versions with either reduced functionality or use
for a limited time.
