I've been using EZNEC Pro/2 to try to model the effects of dielectric
loading on a wire antenna ... specifically a full wave loop on 435 MHz.
I split the sides of the loop up into multiple wires (each with multiple
segments) so I could individually declare a thick dielectric ... i.e.,
insulation in the wires table ... separately for each portion of the
loop. To my surprise the loading effect seems to be greatest at or near
current maximums, not at voltage maximums where I would have presumed
the electric field would have the most effect. This has me greatly puzzled.
Any thoughts?
