Problems solved by technology

[0006] However, the specific application environment of these intelligent communication terminals cannot be determined when they leave the factory, so there is a defect that the simplification of the antenna form does not adapt to the diversification of the application environment. The antenna device is customized, which leads to a series of problems such as poor compatibility of existing intelligent communication terminals and inflexible application fields.

Abstract

The invention discloses a directional diagram reconfigurable antenna device and anintelligent communication terminal. The directional diagram reconfigurable antenna device comprises a first radiation branch, a second radiation branch, a coupling circuit and a short-connection device. The coupling circuit is connected with the front ends of the first radiation branch and the second radiation branch to regulate the resonant frequency of the antenna device. The short-connection device is used to selectively have the tail ends of the first radiation branch and the second radiation branch in short-connection. When the antenna device is required to perform oriented radiation, the tail ends of the first radiation branch and the second radiation branch are separated to develop a V type oriented antenna; when the antenna device is required to perform all-directional radiation, the tail end of the first radiation branch is in short-connection with the tail end of the second radiation branch through the short-connection device so as to develop an all-directional antenna. In this manner, it is possible to reconstruct the antenna from an oriented antenna to an all-directional antenna and to enable the radiation form of the antenna device to be switched optimally according to its practical application environments.

Description

technical field [0001] The invention belongs to the technical field of antenna devices, and in particular relates to an antenna device capable of realizing reconfiguration design for the radiation pattern of the antenna. Background technique [0002] With the rapid development of intelligent communication terminals and the Internet, wireless communication technology has become the main way for people to communicate, not limited to mobile communication terminals such as mobile phones. Communication creates increasing dependence. [0003] The Internet of things (The Internet of things) is an important part of the new generation of information technology, and it is also an important stage of development in the "informationization" era. The Internet of Things is the Internet that connects things. The core and foundation of the Internet of Things is still the Internet. It is a network that extends and expands on the basis of the Internet. Its client end extends and expands to an...
