How to calculate the reactance of a half-wavelength dipole with infinitesimal radius?
The results otained from MOM precedure show that when the radius decrease from 0.005_lambda to 0.0000005_lambda, the impedance will be changed from 97.3014+41.3625i to 77.4771+43.5490i; it seems the reactance, that is, the imaginary part of the impedance, remains relatively constant.
Also, we known sinusoidal current distribution is the exact solution of Hellen's equation when the radius tend to infinitesimal. Thus, the radiation resistance can obtained easily from radiation power, but i cannot find the solution of the reactance in antenna books.
