Abstract

A measurement method using the modulated scattering technique (MST) has been proposed to measure the electromagnetic field rapidly. A simultaneous measurement method using parallel modulated probe (PMP) array has been developed. In this method, each modulated probe element is modulated by a low-frequency modulation signal with different frequency and the modulated signal is combined and received by a broadband microwave receiver. In this report, the simultaneous measurement method using the PMP array is applied to the measurement of the radiation efficiency of antennas to investigate the accuracy of the measurement method
