Experimental study of Ninja array antenna composed of Yagi-Uda antennas

Abstract

Performance of a Ninja array antenna whose backscattering level is lower than that of conventional phased array antennas is demonstrated experimentally. A linear array antenna which is composed of non-identical Yagi-Uda monopole antenna elements is designed. Designed array is fabricated and its scattering/radiation performance is measured. The fabricated array shows low backscattering performance without losing its beam scanning capability.
