[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.

Embodiment 1
[0026] Embodiment one, such as figure 1 As shown, the multi-antenna device of this embodiment mainly includes a radiation body, an antenna matching circuit 110 , a shorting device 120 and other parts. Wherein, four radiation branches 130, 140, 150, 160 are arranged in the radiation body of this embodiment, and the four radiation branches 130, 140, 150, 160 are distributed in the same horizontal plane, and any two adjacent The radiating branches all form a 90° angle, that is, the overall formation of a "ten"-shaped structure, combined with figure 2As shown, the horizontal plane can be divided into four regions, which are defined as: Quadrant I, Quadrant II, Quadrant III, and Quadrant IV. Each radiating branch 130 / 140 / 150 / 160 includes a head end 131 / 141 / 151 / 161, an end 132 / 142 / 152 / 162 and a shorting point 133 / 143 / 153 / 163, defining four radiating branches 130 , 140, 150, 160 adjacent to each other are the head end 131, 141, 151, 161, and the outward end is the end 132, 142, 15...
Embodiment 2
[0043] Embodiment two, such as image 3 As shown, the multi-antenna device of this embodiment also includes main parts such as a radiation body, an antenna matching circuit 310 and a shorting device 320 . Wherein, the radiation body is also composed of four radiation branches 330, 340, 350, 360, and its structure, arrangement, and branch length are the same as those of the four radiation branches 130, 140, 150, 160 in Embodiment 1. The embodiment will not be further described here. Each radiation branch 330, 340, 350, 360 is also provided with a short-circuit point 333, 343, 353, 363, and the short-circuit device 320 controls two or three of the short-point points to connect to the reference ground to change the corresponding radiation. The radial form of the branch. For the arrangement manner and arrangement position of the short contacts 333 , 343 , 353 , 363 on the radiation branches 330 , 340 , 350 , 360 , reference may be made to the relevant description in Embodiment 1...

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...
