Abstract
To provide an inexpensive planar antenna of stable quality which has a circuit with low resistance and in which electrical continuity between the antenna and the electronic part such as IC chip is secured, a planar antenna is made to have a circuit pattern comprised of an antenna part and a connecting terminal part on a resin film, wherein the circuit pattern has a metal layer, a conductive layer provided on the top surface of the connecting terminal part of the metal layer, and a protective layer provided on the top surface of the antenna part of the metal layer and on the section from the side surface to a portion of the top surface of the conductive layer.
Claims7
A planar antenna comprising a circuit pattern comprising an antenna part and a connecting terminal part on a resin film, wherein the circuit pattern has a metal layer, a conductive layer provided on a top surface of the connecting terminal part of the metal layer, and a protective layer provided on a top surface of the antenna part of the metal layer and on a section from a side surface to a portion of a top surface of the conductive layer.
A method of manufacturing a planar antenna, comprising:
- (A) providing a metal layer that constitutes a circuit pattern comprising an antenna part and a connecting terminal part on a resin film, (B) providing a conductive layer on a portion that constitutes the connecting terminal part of the metal layer, (C) providing a protective layer on top of a portion that constitutes the antenna part of the metal layer and on a section from a side surface to a portion of a top surface of the conductive layer, and (D) removing a portion that does not constitute the circuit pattern of the metal layer by etching.
