<P>PROBLEM TO BE SOLVED: To provide an antenna device without causing variation in characteristics in laying around a coaxial cable for antenna power feeding. <P>SOLUTION: The antenna device 10 includes first and second antennas 16, 18 wound on a core member 14. First and second antenna feeding points 21 are disposed at positions displaced to one end side of a core member 14, and a ground point 22 of the first antenna 16 is disposed at a position further displaced to the one end from the feeding point 21. A coaxial cable 114 connected with the feeding point 21 is taken out in a direction where it is separated from the antenna device 10, and an external conductor 114b of the coaxial cable 114 is grounded to the vicinity of the ground point 22. <P>COPYRIGHT: (C)2009,JPO&INPIT |
