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.
Claims9
A planar antenna comprising a circuit pattern comprising an antenna part and a connecting terminal part on a resin film, wherein the circuit pattern comprises:
- a metal layer disposed on the resin film,
- a conductive layer provided on a first portion of the metal layer associated with the connecting terminal part, and
- a protective layer comprising a non-conductive resin provided continuously on a top surface of the conductive layer from a surface of a second portion of the metal layer associated with the antenna part to a peripheral portion of the top surface of the conductive layer through a peripheral side surface of the conductive layer, with an inside of the peripheral portion of the 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 first portion of the metal layer associated with the connecting terminal part, and
- (C) providing a protective layer comprising a non-conductive resin continuously on a top surface of the conductive layer from a surface of a second portion of the metal layer associated with the antenna part to a peripheral portion of the top surface of the conductive layer through a peripheral side surface of the conductive layer, with an inside of the peripheral portion of the top surface of the conductive layer.
