| Abstract(in English) | In recent years, with the spread of indoor wireless LAN, the demand to the improvement in quality of indoor radio communications is increasing. On the other hand, It follows on busy-ization of electric wave use, frequency resources are restricted and realization of the high speed and wide band communication using the millimeter wave is expected. However, when using a millimeter wave for indoor radio communications, a multipath occurs by multiplex reflection from a wall, or a ceiling and a floor, and it has become the cause of degrading transmission quality. In order to solve this problem, the method of improving electric field strength using circular polarized waves is proposed, and much researches are conducted. However, in a former study, it remains for evaluating instant change of electric field strength at the specific position or the specific height, and has not come to search for the distance characteristic and the height characteristic. In this paper, we evaluate the improvement effect by circular polarized waves from both the height direction and distance. |
