Abstract
An external wideband antenna and a wireless communication device are provided in the disclosure. The external wideband antenna includes a radio frequency (RF) coaxial cable, and a first antenna body and a second antenna body which are electrically connected with the RF coaxial cable respectively, where an outer contour of the first antenna body and an outer contour of the second antenna body cooperate to define a tapered slot. In the external wideband antenna provided the disclosure, the outer contour of the first antenna body and the outer contour of the second antenna body cooperate to define the tapered slot, which facilitates generation of a strong coupling current, and in turn a broadening of antenna bandwidth.
