Abstract
A chip antenna includes a substrate, a plurality of helical conductors provided on the substrate, and a pair of terminals provided on the substrate. One of the plurality of helical conductors is connected electrically to one of the terminals, and another one of the helical conductors is connected electrically to the other terminal. Thus, the antenna is of a small size, yet is a single unit which alone is capable of transmitting and receiving electromagnetic waves of a plurality of frequencies.
