132 Dipole Antenna Equations
Shown below is a typical half-wave dipole antenna. The radiation
pattern of a Hertz dipole antenna is perpendicular to the axis of
the antenna. In directions other than the optimum directions, the
antenna is ineffective.
L
λ
To calculate the wavelength of a signal, l or the dipole length, L, or
the frequency, f, of a half-wave dipole antenna, use the following
three formulas:
where:
l = Wavelength (m)
k = Velocity Factor
c = Speed of light = 3 x 10 8 (m/s)
f = Frequency (Hz)
L = Length of the Dipole (m)
