<P>PROBLEM TO BE SOLVED: To provide an antenna which is capable of transmitting/receiving a radio wave in a wide frequency band and in which the level of a frequency band to be used can be freely and finely adjusted. <P>SOLUTION: An antenna 10A comprises an unbalanced power feeding member 11, a resonance conductor 12, and a ground conductor 13. The resonance conductor 12 is formed of first and second resonance conductor parts 20a and 20b which extend forward in an axial direction of the unbalanced power feeding member 11 in parallel with a power feeding part 18. The ground conductor 13 is formed of a fixed part 25 electrically connected to the unbalanced power feeding member 11, and first and second ground conductor parts 26a and 26b which extend backward in the axial direction of the unbalanced power feeding member 11 in parallel with a non-power feeding part 19. <P>COPYRIGHT: (C)2013,JPO&INPIT |
