A wideband antenna includes a first substrate, a second substrate, a ground plane, an exciting element, a connection element, a first branch, a second branch, and a coupling branch. The ground plane is disposed on the first substrate. The exciting element is disposed on the second substrate and has a feed point coupled to a signal source. The connection element is disposed on the second substrate and coupled to the ground plane. The first branch is disposed on the second substrate and coupled to the connection element. The second branch is disposed on the second substrate and coupled to the connection element. The coupling element is disposed on the second substrate and coupled to the connection element. The distance between the coupling element and the second branch is smaller than 5 mm.

Wideband antenna

A mobile communication device for operating in LTE and WWAN bands is provided in the invention. The mobile communication device includes a system circuit board and an antenna. The system circuit board includes a system ground plane. The antenna includes: an antenna substrate, substantially parallel to the system ground plane; a first radiation element, disposed on the antenna substrate; a second radiation element, disposed on the antenna substrate; an antenna ground plane, disposed on the antenna substrate, and coupled to the system ground plane; and a transmission line, disposed on the antenna substrate, coupled to the first and second radiation elements, and having a feed point. The mobile communication device is further configured to accommodate a data transmission component.
