Electric field probe

The electric field probe is used for the point-by-point measurement of the microwave fields. It is used in experiments on basic principles and in the investigation of field distribution in the parallel plate line. Careful set-up ensures that only the electric field strength is detected. The detector is not activated by the magnetic field. The AF signal is proportional to the square of the magnitude of the electric field strength at the location of the dipole. Due to the small dimensions of the probe, interference of the field to be investigated is minimal. The electric field probe consists of a short dipole antenna, a detector diode and a high impedance AF-feeder.
