Abstract
A planar antenna has a circuit pattern including an antenna part and a connection terminal part on a plastic film, in which the circuit pattern has a metal layer and a heat-sealable conductive layer provided on a surface layer of a connection terminal part of the metal layer. The planar antenna is obtained by forming a circuit pattern including a metal layer on a plastic film, providing a heat-sealable conductive layer in a connection terminal part of the circuit pattern, and then removing an unnecessary part with etching.
Claims13
A planar antenna having a circuit pattern comprising an antenna part and a connection terminal part on a plastic film, wherein the circuit pattern has a metal layer and a heat-sealable conductive layer provided directly on a surface layer of a connection terminal part of the metal layer, wherein the conductive layer is a resin layer containing a conductive particle or a conductive fiber.
A manufacturing method of a planar antenna including a step A of providing a metal layer constituting a circuit pattern comprising an antenna part and a connection terminal part on a plastic film,
- a step B of providing a protective layer of antenna part on a part constituting an antenna part of the metal layer,
- a step C of providing a heat-sealable conductive layer directly on a part constituting a connection terminal part of the metal layer, and
- a step D of removing a part that does not constitute a circuit pattern of the metal layer with etching after the step B and the step C.
