Antenna field calibration laboratory for RF electromagnetic field meters

During recent years, the pronounced electromagnetic pollution of the environment makes it ever more necessary to increase the number of calibrated field strength meters aiming at a better protection of the people and equipment against the electromagnetic radiations. The paper presents the calibration procedure and necessary equipment of RF electromagnetic field meters in the antenna field inside the semi-anechoic chamber (SAC) of ICMET. The whole calibration process is automatically controlled by a computer. Some experimental results necessary to certify the calibration system such as field uniformity, antenna conversion factor and measurement uncertainty are also presented
