| Abstract(in English) | The authors have proposed an unintended power radiation technique using adaptive array antenna with a wide and deep null created to unintended radiated direction in the antenna directivity. This paper investigates a relationship between number of antenna elements of adaptive array antenna and created antenna null width of the proposed technique, thus clarify the necessary number of antenna elements of the adaptive array antenna in order to suppress unintended radiation to a specific untargeted point in indoor wireless communication environment. With computer simulation, the relationship between the number of antenna elements and the null width is calculated, on the other hand with propagation measurement, radiation angle spread to a single point is measured, this paper concludes that the necessary number of antenna elements in order to suppress unnecessary radiation to a single point is 4 with the proposed method. |
