Abstract
A double loop antenna includes a source loop comprising: a spiral-shaped conductive source coil pattern disposed on a top surface of a board, and a source capacitor pattern comprising symmetrical conductive patterns disposed on the top surface and a bottom surface of the board; and a resonance loop comprising: a spiral-shaped conductive resonance coil pattern disposed on the bottom surface of the board, and a resonance capacitor pattern comprising symmetrical conductive patterns disposed on the top surface and the bottom surface of the board, wherein the source coil pattern and the resonance coil pattern are formed on different surfaces of the board.
