Broadband antenna and wireless communication device empolying same

A wireless communication device, comprising:

• a circuit board;
• a holder;
• and
• a broadband antenna positioned on the holder and comprising:
• a main radiator comprising a main radiating portion, a first radiating arm extending from the main radiating portion, and a second radiating arm extending from the main radiating arm, the first radiating arm forming a first current path to generate a first high frequency mode, the second radiating arm forming a second current path to generate a second high frequency mode;
• a grounding unit that is grounded via the circuit board;
• a feeding unit extending from the main radiating portion and electronically connected to the circuit board;
• and
• a resonating unit connected to the grounding unit, wherein the resonating unit surrounds and is positioned separate from the second radiating arm, the resonating unit resonates with the main radiator to generate two different low frequency bands corresponding to two coupling currents.
