PROBLEM TO BE SOLVED: To maintain a satisfactory antenna characteristic even when an antenna is unable to be disposed at a desired position or when a plurality of antennas are disposed in a device.SOLUTION: An antenna 10 includes: a printed wiring board 20; an antenna circuit 30 disposed on a predetermined end part of the printed wiring board 20 for transmitting and receiving a radio wave having a wavelength λ; and a series resonance circuit 40 disposed at a predetermined end part of the printed wiring board 20 in a position apart from the antenna circuit 30 in a predetermined distance. When the antenna 10 is installed on an XY plane, the predetermined end part extends to a Z direction orthogonal to the XY plane. |
