Abstract (en)
A flat dual-band antenna includes a radiating unit (21), a grounding unit (22) and a feeding unit (23). One end of the grounding unit (22) is connected with the radiating unit (21), and the other end of the grounding unit (22) is grounded. The grounding unit (22) has a gradual width-changing section. The radiating unit (21) is divided into a first radiating portion (212) and a second radiating portion (213) by the grounding unit (22). The feeding unit (23) is connected with the junction of the first and second radiating portions (212,213), and electrically connected with the radiating unit (21) and the grounding unit (22).
