Non-contact type IC card, antenna and antenna frame for IC card
First Claim
1. An antenna for non-contact type IC card, said antenna comprising:
- a plane coil formed by punching or etching a thin metal plate in such a manner that a conductor line is wound several times on substantially the same surface; and
at least one projection integrally formed with said conductor and extending therefrom inwardly or outwardly so as not to contact an adjacent loop of said conductor line, said projection being located at any desired position and used as a suction pad, an alignment mark or a positioning guide when said plane coil is sucked or positioned.

Abstract
An antenna for a non-contact type IC card is provided.
A plane coil is formed by punching or etching a thin metal plate in such a manner that a conductor line is wound several times on substantially the same surface. The plane coil has respective terminals at innermost and outermost ends. The innermost terminal is provided with accommodation hole, in which a semiconductor element having electrode terminals is arranged. A circuit film comprises an insulating resin film and a circuit pattern formed on the insulating resin film. The circuit pattern electrically connects the electrode terminals of the semiconductor element to the terminals of the plane coil, respectively. At least one projection is integrally formed with the conductor and extending therefrom inwardly or outwardly so as not to contact an adjacent loop of the conductor line. The projection is located at any desired position to be used as a suction pad, an alignment mark or a positioning guide when said plane coil is sucked or positioned.
