How Do You Calculate Fields of a Hertzian Dipole Using MATLAB?

[rk2ray]

Homework Statement

a hertzian dipole antenna has a length of 5 mm and carries a 50 MHz current of 2 A. Find the magnitude of the electric and magnetic fields at a distance 15 cm away from the antenna and theta=30 degree.

Homework Equations

Attached the equations

The Attempt at a Solution

I tried to do manual calculations but need MATLAB code

Given that
r = 15cm = .15 m
θ=30°
dl=5mm =.005 m
Io= 2A
f=50 MHz

ω = 2∏f = 3.14 x 10^8 rad/s

β = ω/c = 1.04 /m

λ = 2∏/β = 6 m

η = 120∏

Etheta = (μIo/4∏r) * sinθ * e^(-jβr)*[ sin(βL/2) - j cos(βL/2)]Ephi = (μIo/4∏r) *cosθ * e^(-jβr)*[ cos(βL/2)- j Sin(βL/2)]Htheta = (Io/4∏r) *sinθ *e^(-jβr)*[ cos(βL/2) + j sin(βL/2)]Hphi = (Io/4∏r) *cosθ *e^(-jβr)*[ -sin(βL/2) + j cos(βL/2)]E = sqrt((Etheta^2)+(Ephi^2))H = sqrt((Htheta^2)+(Hphi^2))
