| Abstract(in English) | In this paper, we propose an accurate measurement method for impedance characteristics of an antenna on a portable telephone. We use the fiber optics for feeding cables to remove the undesired influence of the coaxial cable. We show the measurement system using the network analyzer together with the fiber optics can achieve results as accurate as that of the conventional coaxial cable, and the influence of the fiber optics is negligible. The measurement results of a monopole antenna on a rectangular box show the validity of the measurement system. On the other hand, the conventional method using the coaxial cable affects the measurement results. |
