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.
