Abstract
PROBLEM TO BE SOLVED: To provide a flat antenna arrangement having a ground earth plate and a radiator. SOLUTION: In switch element 11, at a first (lower) resonance frequency of an antenna arrangement, a voltage minimum is present in a connection part of a radiator with a ground plate, and a first voltage maximum is present in a region of the other end (unsupported end part) of the radiator, and a connection having low impedance can be carried out by this structure to be set as above. The switching element 11 is disposed near the unsupported end part of a radiator 3, between the radiator 3 and a ground plate 2, and a point where the switch element is connected with the radiator 3 is set to that the switch element 11 is energized, and the radiator 3 is disposed so as to have a desired second resonance frequency which is higher than the first resonance frequency.
