发明名称 Antenna apparatus
摘要 An antenna apparatus has a first antenna element and a second antenna element branched from one power feed point. The first antenna element and the second antenna element, which have different lengths, are arranged nearly in a loop as a whole with a predetermined clearance provided between distal ends thereof. The first antenna element and the second antenna element are arranged in such a way that the end faces of the distal ends thereof do not face each other with a lengthwise direction of the end face of the distal end of the first antenna element being approximately orthogonal to a lengthwise direction of the end face of the distal end of the second antenna element. Therefore, the antenna apparatus can suppress electric coupling of a plurality of antenna elements which transmit and/or receive radio waves of different frequency bands.
