Abstract:
1. A dual-band antenna, comprising: an impedance matching control element comprising a first end and a second end; a first connection part; a first radiation element operating in a first frequency band, electrically connected to the first end via the first connection part, and extending along a first direction having an obtuse angle with respect to a longitudinal direction of the first connection part, wherein the first radiation element and the impedance matching control element form a first slot therebetween and having a close end configured at the first connection part; a second connection part; a second radiation element operating in a second frequency band and comprising a first extension part electrically connected to the second end via the second connection part and extending along a second direction having an obtuse angle with respect to a longitudinal direction of the second connection part, and a second extension part electrically connected to the first extension part and forming an acute-angled slot between the second extension part and the first extension part, wherein the second radiation element and the impedance matching control element form a second slot therebetween and having a close end configured at the second connection part; and a ground element electrically connected to the impedance matching control element and the second radiation element.
