Question

Model the antenna in NEC .Show the radiation pattern. Please show the steps of how to do it in NEC.

Design a resonant ring of N turns, with a circumference of λ / 4, a frequency of 10 MHz. The ring will be powered by a two wire transmission line, with impedance 300 ohm characteristic.

Disregarding proximity effects, determine:

a) the nearest integer number of turns so that the antenna impedance
be 300 ohms

b. the input impedance of the antenna
c. the reflection coefficient
d. the VSWR on the transmission line

All in NEC
