<P>PROBLEM TO BE SOLVED: To configure an antenna in simple structure not using a dedicated antenna element. <P>SOLUTION: An antenna comprises: a first conductor 2b (2d) which has first line length from a starting point 4 to a turnaround point 3; and a second conductor 2b (2d) which has second line length in a direction from the turnaround point 3 to the starting point 4 and is electrically connected to the first conductor on the turnaround point 3. Additionally, the antenna is configured so that a first received signal of a first frequency is received with first antenna length including both the first line length and the second line length, and a second received signal of a second frequency is received with second antenna length including only one of the first line length or the second line length. <P>COPYRIGHT: (C)2012,JPO&INPIT |
