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.

External wideband antenna and wireless communication device

A method for detecting operation state of a mobile terminal to adaptively adjust antenna state, comprises: step 1, outputting a detecting result when the external object is detected to be in proximity to or contacting a predetermined location of the mobile terminal; step 2, acquiring the operation state of the mobile terminal based on the detecting result; step 3, adjusting the antenna state based on the operation state. The present invention also discloses a sensing system capable of determining the usage scenario of the mobile terminal used by users; by using a design of integrating a sensor unit to the complete device, it can correctly determine a present method and scenario of a hand-held mobile terminal being used by user, so that the adjustable antenna can make a selection for a present user scenario better, and improve the radio-frequency performance of the complete device and the user experience.
