ABSTRACT:
An antenna device comprises an antenna element formed in a sufficiently shorter length as compared with the wavelength of transmission or reception wave, a resistor, a matching circuit including at least a reactance element, and an output terminal connected to outside, which are connected in series in this sequence. As a result, an antenna device of smaller size and small loss is obtained.
