A weight determining apparatus is disclosed. The weight determining
apparatus includes two or more antenna elements that receive a test wave
transmitted by one or more test wave sources prepared outside of a
phantom that simulates an object that attenuates a radio wave, the
antenna elements being prepared in a mobile terminal. The weight
determining apparatus further includes a weight determining unit that
determines weights for the antenna elements such that a signal received
by the antenna elements as a whole may be maximized.
