<P>PROBLEM TO BE SOLVED: To provide a composite antenna device capable of canceling the physical influence of a bar antenna to a planar antenna. <P>SOLUTION: The composite antenna 10 has: an antenna base 20 having a main surface 20a and first and second ends 20b, 20c opposing each other; the bar antenna 30 including a metal body 31 erected at the first end side of the antenna base; and the planar antennas 40, 50 mounted onto the main surface of the antenna base between the first and second ends of the antenna base. A metal member 70 provided at the second end side of the antenna base is provided at a prescribed position and has a size so that the physical influence of the bar antenna 30 to the planar antenna 50 is canceled substantially. The metal member is composed of a metal rod body 70 erected at a prescribed position from the upper portion of the main surface 20a of the antenna base. <P>COPYRIGHT: (C)2008,JPO&INPIT |
