Transparent antenna and rf tag

Abstract

Provided is a transparent antenna comprising a transparent base material, an antenna part, and a joint part electrically bonded to the antenna part, the antenna part and the joint part being arranged on the transparent base material, wherein the joint part has a first conductive pattern and a first opening part without the first conductive pattern formed thereon, the antenna part has a second conductive pattern and a second opening part without the second conductive pattern formed thereon, surface free energy E1 of the first conductive pattern is 60 mJ/m2 or less, and surface free energy E0 of the transparent base material at the first opening part is larger than the surface free energy E1.

Dependencies are inferred from the claim text.
