Abstract
A compact non-directional chip antenna. The chip antenna includes a rectangular-parallelopiped base made of printed circuit boards (specific inductive capacity: about 2 to 6) having a glass epoxy resin or glass fluororesin as main constituents, a conductor, made of copper or a copper alloy, which is wound in the shape of a spiral inside the base along the direction of the length of the base, and a power feeding terminal, for applying a voltage to the conductor, on the surface of the base. One end of the conductor forms a power feeding section and is connected to the power feeding terminal. The other end of the conductor forms a free end inside the base.
