摘要（英）：

A dielectric antenna and the communication device including the antenna are disclosed, wherein a dielectric substrate has a first face, a second face opposing to the first face, and side faces connecting the first face and the second face. A grounding electrode is provided on the first face. A first radiation electrode is configured to resonate with an electromagnetic wave having a first frequency. The first radiation electrode extends parallel to at least one of the second face and the side faces. A feeder electrode extends parallel to one of the side faces, and is electromagnetically coupled with the first radiation electrode. A second radiation electrode is configured to resonate with an electromagnetic wave having a second frequency. The second radiation electrode extends parallel to one of the side faces and is electromagnetically coupled with at least one of the first radiation electrode and the feeder electrode. One end of the feeder electrode serves as a terminal for supplying power to the first radiation electrode and the second radiation electrode. Said communication device comprises a communication circuit processing data communication with the exterior communication device, and a dielectric antenna according to the invention, which form circuit connection.
