1. A non-contact communication antenna comprising:
- a first antenna pattern that is formed on one surface of a base material; and
a second antenna pattern that is formed on a back surface of the one surface of the base material,wherein the first antenna pattern includes a first coil section and a first electrode section,wherein the second antenna pattern includes a second coil section and a second electrode section,wherein capacitance of the first electrode section and the second electrode section compensates a change in capacitance depending on a formation situation of the first coil section and the second coil section.

Abstract
There is provided a non-contact communication antenna including a first antenna pattern that is formed on one surface of a base material, and a second antenna pattern that is formed on a back surface of the one surface of the base material. The first antenna pattern includes a first coil section and a first electrode section. The second antenna pattern includes a second coil section and a second electrode section. Capacitance of the first electrode section and the second electrode section compensates a change in capacitance depending on a formation situation of the first coil section and the second coil section.

12. A method for manufacturing a non-contact communication antenna, the method comprising:
-
forming, on one surface of a base material, a first antenna pattern having a first coil section and a first electrode section; and forming, on a back surface of the one surface of the base material, a second antenna pattern having a second coil section and a second electrode section, wherein the first electrode section formed in the first-antenna-pattern forming step and the second electrode section formed in the second-antenna-pattern forming step compensate a change in capacitance depending on a formation situation of the first coil section and the second coil section in the first-antenna-pattern forming step and the second-antenna-pattern forming step. - View Dependent Claims (13, 14)
