We examine the fast estimation method of the electric field using the antenna system that arranges the cross polarization patch antenna on a cubic all side in order to understand the electric wave propagation structure aiming at an efficient installation of the base station in the indoor environments. The general electric field measurement using the electric field probe has the problem that the influence of the standing wave is requires the micro interval measurement and it’s not efficient measurement. In this paper, we evaluated basic characteristics of this antenna system by the prototype and we confirmed that the radiation characteristic of the prototype is roughly satisfied in spite of the influence of the feeding cables. Next, we measure the electric field in the standing wave environments composed of 2 waves and multiple waves using the prototype, and we confirm the possibility that doesn’t need the measurement at the micro interval. |
