Antenna device capable of reconstructing directional diagram and intelligent communication terminal

Abstract

The invention discloses an antenna device capable of reconstructing a directional diagram and an intelligent communication terminal; the antenna device comprises a V-type antenna, a first coupling circuit connected with a signal feed point of the V-type antenna, and a short circuit unit; the V-type antenna comprises a first radiation branch and a second radiation branch; the short circuit unit is connected with the second radiation branch, and used for controlling the second radiation branch to selectively connect with a reference ground; when the short circuit unit controls the second radiation branch to connect with the reference ground, the first radiation branch forms a single pole omnidirectional antenna, thus realizing omnidirectional radiation. An existing V-type directional antenna is added with the short circuit unit capable of controlling one radiation branch of the V-type antenna to selectively connect with the ground, thus allowing the antenna device to change from the original orientation radiation to the omnidirectional radiation, reconstructing the antenna mode from the directional antenna to the omnidirectional antenna, realizing compatibility design of the antenna device, and allowing the antenna device to preferably switch according to 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...

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.
