Abstract :
A new vector measurement method of electromagnetic field distribution in space based on a scalar measurement similar to the six-port concept is presented. In addition to transmitting and receiving, the antenna system utilizes a reference antenna continuously irradiating the receiving antennas via a coherent signal with several phase shifts. The functionality of the method was verified experimentally using three antennas in the 8 - 12 GHz frequency band. The method is applicable to imaging systems or for measuring the near field of antennas, etc.
