<p>An antenna circuit comprises: a substrate; an antenna coil formed on only one side surface of the substrate; and a low-profile crossover element to electrically mutually connect an internal end part and an external end part of the antenna coil by bridging at least one turn of the antenna coil. The crossover element includes: an electric insulation layer which is formed on the turn of the antenna coil or is formed to be adjacent thereto; a first electric conductive layer which is formed on the electric insulation layer; and a second electric conductive layer which is formed on the first electric conductive layer and is made of different types of electric conductive materials, thereby improving the lifespan of the antenna element while maintaining the profile of the crossover element to be minimum.</p> |
