Abstract

To provide a plurality of antenna elements in a limited space so that the antenna elements do not impact one another. [Solution] An antenna substrate (12) is arranged on an antenna base (11) so that it stands erect, and a first element (15) and a second element (16) are formed on the antenna substrate (12). A top section (14) is provided on the top of the first element (15), a coil unit (13) is provided on the bottom of the first element (15), and the entire assembly resonates in the FM frequency. The height of the top section (14) from the antenna base (11) is set at 20mm or greater and the gap between the first element (15) and the second element (16) is approximately 10mm or greater so that the first element (15) operates efficiently in the AM frequency.
