Embodiment Construction

[0041] Please refer to figure 1 , is a schematic diagram of an embodiment of the multi-antenna system of the present invention. In this embodiment, the multi-antenna system is printed on the substrate 100 , which includes the ground metal layer 200 , the first antenna 10 , the second antenna 20 and the metal ground wall 40 . Wherein, the first antenna 10 , the second antenna 20 and the metal ground wall 40 are electrically connected to the same side of the ground metal layer 200 . The ground metal layer 200 is provided with a slot 30 . In this embodiment, the substrate 100 can be a printed circuit board, which is partially coated with a metal layer (such as figure 1 The shaded part shown) can be used as the ground metal layer 200 , the first antenna 10 and the second antenna 20 . In this embodiment, the shape of the ground metal layer 200 is not limited, and at least includes the same side as the first antenna 10 , the second antenna 20 and the metal ground wall 40 .

Abstract

A multi-aerial system is printed on a substrate, and comprises a grounding metal layer, a first antenna, a second antenna, a metal ground wall and a groove hole, wherein the first antenna, the second antenna and the metal ground wall are connected with the grounding metal layer, and the groove hole is formed in the grounding metal layer. The metal ground wall is arranged between the first antenna and the second antenna. The grounding metal layer is electrically connected to the first antenna, the second antenna and the metal ground wall, and the groove hole formed in the grounding metal layer is located between the first antenna and the metal ground wall. The groove hole and the metal ground wall are arranged between the two antennas, so that electromagnetic interference between the two antennas is effectively prevented.

Description

technical field [0001] The present invention relates to an antenna, in particular to a multi-antenna system. Background technique [0002] At present, most wireless communication products, such as routers (router devices), adopt a multi-antenna system, that is, more than two antennas are used on the same frequency band. However, because the distance between the antennas is too close, the antennas will interfere with each other, resulting in the degradation of the signal quality received by the antennas. Therefore, how to effectively prevent the interference generated between the antennas and make them have excellent reception quality is a major research topic in the current industry. Contents of the invention [0003] In view of this, it is necessary to provide a multi-antenna system that can effectively prevent interference between antennas. [0004] A multi-antenna system provided in an embodiment of the present invention is printed on a substrate, and includes a groun...
