PURPOSE: A dual loop antenna is provided to reduce a manufacturing cost by lowering conductor consumption due to a device of a loop. CONSTITUTION: A dual loop antenna includes a first loop, a second loop, and a feeding line. The first loop(11) has a first radius according to a length of a first wavelength of a first frequency. The second loop(12) has a second radius according to a length of a second wavelength of a second frequency. The second loop is positioned in the same plane as the first loop. The feeding line(13) is connected to the first loop and the second loop, and forms a feeding point. |
