Abstract :
Three methods for measuring total radiated power of GSM handsets have been evaluated by an experimental comparison. Evaluated methods were scattered field measurement method, stirred-mode chamber method and three-dimensional pattern integration method (3-D PIM). The parameter investigated was total radiated power in talk position beside a torso phantom and in free space. The handset antenna performance testing including a human body phantom is a novel application for stirred-mode chambers and is presented. Based on the evaluation of the three methods, the 3-D PIM seems to be the most suitable method for antenna performance measurements of mobile terminals
