Reconfigurable multi-antenna device and intelligent communication terminal

Abstract

The present invention discloses a reconfigurable multi-antenna device and an intelligent communication terminal. The reconfigurable multi-antenna device comprises four radiation branches, an antenna matching circuit and a short-connection device; when electromagnetic waves required to be received are evenly distributed in the space, the short-connection device controls three of the radiation branches and makes the same communicated with reference ground, and the remaining radiation branch constitutes a unipolar omnidirectional antenna; and when the electromagnetic waves required to be received are non-uniformly distributed in the space, the short-connection device controls two adjacent radiation branches and makes the same communicated with reference ground, and the remaining two adjacent radiation branches constitute a V-shaped directional antenna, and a directional radiation magnetic field having a maximum radiation direction which points to or approach a direction in which the distribution of the electromagnetic waves in the space is most intensive is formed. With the reconfigurable multi-antenna device and the intelligent communication terminal of the invention adopted, multi-directional coverage of the V-shaped directional antenna can be realized, so that the omnidirectional gain of the antenna is increased indirectly; and the antenna device can be switched between directional radiation and omnidirectional radiation optimally, and the reconfiguration of the antenna from a directional antenna to an omnidirectional antenna is realized.

Description

technical field [0001] The invention belongs to the technical field of antenna devices, and in particular relates to a multi-antenna device capable of realizing reconfiguration design of antenna pattern. 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 an ever-increasing dependency. [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 any item 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.
