An antenna structure includes a feed section, a ground section, a first radiator, a second radiator, and a third radiator. The first radiator and the second radiator are both connected to the feed section. The third radiator is connected to the ground section. The first radiator defines a first slot. A second slot is defined between the second radiator and the third radiator. The third radiator defines a third slot. The third slot communicates with the second slot. Current is coupled from the first radiator and the second radiator to the third radiator via the first slot, the second slot, and the third slot.

Antenna structure and wireless communication device using the same

A multiband antenna includes a feed end, a first ground end, a second ground end, a ground path, parasitic member, a first resonating member, and a second resonating member. The ground path is connected between the feed end and the first ground end. The first resonating member operates at a low frequency resonating mode. The second resonating member operates at a high frequency resonating mode. The second resonating member includes a first bent portion and a second bent portion. The first bent portion is coupled with the parasitic member to widen a bandwidth of the second resonating member at the high frequency resonating mode. The second bent portion is coupled with the first resonating member to reduce an electrical length of the first resonating member.

Multiband antenna

An exemplary wireless communication device includes a circuit board, a metal board, and a display module. The circuit board includes two groups of connecting terminals. The metal board is located on the circuit board and includes two metal bodies. The display module is located on the metal board. One metal body is electronically connected to one group of connecting terminals. The other metal body is electronically connected to the other group of connecting terminals.
