ABSTRACT:
A dipole antenna includes a plurality of parallel metal wires as its basic structure, and a plurality of identical or similar unit circuits arranged in a row in an extending direction of the plurality of metal wires and connected with each other. The unit circuits each have a tie portion that connects the metal wires with each other via at least one first inductor, and at least one first capacitor provided on at least one of the metal wires. The plurality of metal wires each have a base portion and an extended portion, and the plurality of metal wires are each bent such that the extended portion extends at an angle of 90 degrees with respect to the base portion.
