  • The equivalent capacitance method is the main calibration method for monopole antennas given in CISPR 16-1-6. The principle is to use an equivalent capacitor to simulate an actual monopole element for the calibration of the corresponding antenna factor, and the electric capacity of this equivalent capacitor is equal to the capacity of the monopole antenna itself. Based on the working principle of the equivalent capacitance method, a miniaturized and highly versatile antenna calibrator is designed. Simulation and experimental results show that the calibrator can be well applied to the calibration work of the monopole antenna. The evaluation process and results of the measurement uncertainty of the method are given, and the results show that the extended uncertainty of the measurement results is about 1.7 dB (k=2) when the antenna factor of the monopole antenna is calibrated by this device.
