Abstract

A commonly used method of calibrating sensors for high frequency electric fields is based on the use of closed TEM-waveguides. But this method does not allow the determination of errors produced by any coupling between the sensor and the waveguide. A new method of electric field sensor calibration is presented which allows the determination of coupling errors. This is done by a superposition of radiated and guided waves and this error can be quantified by measurements. Consequently a higher accuracy in the representation of electric fieldstrength and calibration of sensors and antennas can be obtained.
