Abstract

This paper examines the possibility of 1 mW power transmission to extremely tiny chips through a wide aperture 30-GHz phased array. We assume that the chip size is 0.5 by 0.5 mm and do not have external antennas. Then we reveal that the optimal frequency is 30 GHz in case that the phase array length is fixed to 30 cm and demonstrate its feasibility. In addition, we realize a two-dimensional phased array by using new splitter and show that the system can transmit power more efficiently.
