Abstract

AbstractThe indoor random field measurement (RFM) method is useful for measuring the radiation efficiency of a small built‐in antenna operating in the vicinity of electric gear and the human body. In this paper we report on the first experimental check of the accuracy of the indoor RFM method. We introduce the DDD value as a figure of merit for the measurement site. A new method of using radiowave scatterers is also proposed to improve the accuracy of the measurement. We find that the new indoor RFM method is effective for measuring the radiation efficiency of a small antenna.
