ABSTRACT:
A dipole antenna includes a plurality of generally parallel metal wiring lines, and a plurality of identical or similar unit circuits arranged in a row along the extending direction of the metal wring lines and connected with one another. Each unit circuit includes a connection portion for connecting the metal wiring lines together via at least one first inductor, and at least one first capacitor inserted into at least one of the metal wiring lines. The plurality of unit circuits are identical unit circuits. Alternatively, the plurality of unit circuits include unit circuits operable in the right-hand system and unit circuits operable in the left-hand system.
