An antenna module is provided and includes two feeding parts and having different frequencies of feeding on a circuit board. A first feeding radiation electrode is connected to the feeding part on a lower frequency side and performs an antenna operation. A second feeding radiation electrode is connected to the feeding part on a higher frequency side and performs an antenna operation. The first and second feeding radiation electrodes electrically connected, and the second feeding radiation electrode is smaller than and on the first feeding radiation electrode with an insulating part therebetween. The first feeding radiation electrode is configured to serve as an electrode that also performs an antenna operation of the second feeding radiation electrode, in such a manner that the second feeding radiation electrode performs an antenna operation in which the second feeding radiation electrode and the first feeding radiation electrode are electrically coupled to each other. |
