How to simulate printed antenna?

[jjantenna]

How to simulate single side printed antenna on PCB using NEC? I only care about the radiation pattern, so NEC (MOM based) could be the fastest way. I was told that the printed strip conductors are transformed to circular conductors coated with dielectric or magnetic covers based on the principle of quasi-static energy equivalence, with radiation properties then solved by the usual method of moments for wire antennas. But how?

The following book has this information but I haven't got one:
B. D. Popovic, CAD of Wire Antennas and Related Structures. New York: Wiley, 1991, ch. 2.

Can anyone help me out?

Its a good idea. In 4nec2 i have seen planar GND plane. that means another plate has to be defined on it and to be exited properly to get the result for suspended antenna. SuperNEC supports substrates... :idea: ..those who are using superNEC may be able to give a better answer.

I am not sure but dosen't wipl-d use a NEC like code ? It gives o/p very quickly and inputs are very similar to NEC. It can simulate patch antenna.

Thank you g86. Frankly speaking, this is my first time hearing about the mysterious wipl-d. I am still interested to know the equalivent length/radius of the wire relating to the thickness/dielectric constant/width of the substrate. Anyone who has that book could tell us the something.

I might be a little late for this but may I refer you to the following paper:

I am still not very familiar with this technique so if you have had any clues, I will be interested.

Dear Element7k
it'a pity that the link you provide doesn't work to me )"
