DIPOLE ANTENNA

摘要

A dipole antenna comprises a first radiation element (a part of 20) which has a power supply unit (40) and which is long in a reference direction, a second radiation element (the other part of 20) which allows both ends of the first radiation element to be connected and which is long in the reference direction, and a non-power supply radiation element (30 and the like) which is arranged in opposition to a plane surface formed by a linear portion of the first radiation element and a linear portion of the second radiation element and which does not have the power supply unit.
