An automatic technique for calibrating electrically small electroma etic field sensors utilizing a transmission cell is p r e s e n t 2 The method is fast to use and allows probe calibration immediately prior to use at current ambient conditions. This greatly simplifies calibration and eliminates errors due to environmental conditions. Also eliminated are human errors associated with standard manual calibrations.Also presented is a method of reducing the sensor calibration data to less than 10 numbers while maintaining a high degree of accuracy. The data reduction technique can be expected to yield errors of less than 2 dB over two decades of frequencies and field strengths. The automatic calibration and data reduction techniques are demonstrated on a diode-loaded dipole antenna system.
