Abstract:
1. A dielectric antenna, comprising: a dielectric substrate, having 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 provided on the first face; a first radiation electrode, configured to resonate with an electromagnetic wave having a first frequency in a first frequency band, the first radiation electrode being extended parallel to at least one of the second face and the side faces so as to serve as an inverted-F antenna; a feeder electrode, extended parallel to one of the side faces, and electrically connected with the first radiation electrode; and a second radiation electrode, configured to resonate with an electromagnetic wave having a second frequency in a second frequency band, wherein the second frequency band is distinct from the first frequency band, the second radiation electrode being extended parallel to one of the side faces and separated from the first radiation electrode and the feeder electrode so as to be electromagnetically coupled with at least one of the first radiation electrode and the feeder electrode, wherein one end of the feeder electrode serves as a terminal for supplying power to the first radiation electrode and the second radiation electrode.
