The Cylindrical Dipole as a Sensor or Probe

The cylindrical dipole is shown to be frequency-independent over the range of electrical lengths kh ' 1 for resistive loads in the range 3.77 -' RL C 377 fl when used to measure the time derivative of the electric field. It can also be used to measure the electric field in the frequency domain and used as a standard for calibrating sensors with regard to their frequency independence over selected ranges of frequency.
