PROBLEM TO BE SOLVED: To provide a dipole antenna of a multi-point power supply system using a printed board. SOLUTION: Sets of conductors connected together with feeding lines are provided on the front and rear of a board, and some of the conductors located on one side of the board are connected to some of the conductors located on the other side of the board with a conductive member. The conductors are provided on both the sides of the board, so that a pair of feed lines are not required to be provided on the same side (a pair of feed lines are not required to cross each other at different levels). The antenna is formed of a single board, so that the antenna is improved in productivity and applied to a multi-band antenna etc. COPYRIGHT: (C)2007,JPO&INPIT
