摘要：
A flip-open type mobile wireless device able to receive a signal of the same polarized wave both in an open state and a closed state of a movable part including an antenna with respect to a fixed part, provided in the antenna with a first feeding point and a second feeding point for handling different polarized waves, an open/close detecting unit for detecting which of the opened/closed states the movable part is in relative to the fixed part, and a feed switching unit for feeding electric power to the first feeding point when detecting the open state thereof and feeding electric power to the second feeding point when detecting the closed state thereof.
