Question regarding 4NEC2 simulation.

[yvonne82]

Hi,

I know it is a basic question. Why (using 4NEC) I need to divide a half wavelength dipole with a number of segment instead of using just 1 segment to simulate it? In examples given in 4NEC2, they divide the dipole with 9 segments.

Thanks.

Hi there!

It's becouse the software can calculate the antenna more easily by approximating the current distribution into 9 discrete currents, which are constant over a single segment.

Hope this helps,

Cheers!

9 segments are not enough. Please increase the number of segments to improve the accuracy.
Up to 1000 segments, the simulation time is not going to be a major problem.

simulation 4NEC2 is simple software
use supernec (it is run with matlab 6.5)
the using of supernec easiliy than 4nec2
in supernec you set the segmantation easily and what you want.
