| Abstract(in English) | The array antenna weight determination method using random inner test source (RITS) has been developed in order to improve radiation efficiency of distributed feed for mobile handsets. This method spends a lot of time to scan a random inner test source in the liquid phantom. In this paper, we proposed array type of RITS method that can reduce scan points in order to realize fast measurement and experiment. Three-element array RITS having low coupling was used in this experiment. The field response ratio was obtained by using the array RITS. It is clarified that the experimental results of this method have good agreement with that of conventional method. |
