Embodiment Construction

[0039] Figure 5 A schematic diagram showing a multi-antenna communication device according to an embodiment of the present invention. Such as Figure 5 As shown, the multi-antenna communication device 500 is a dual-antenna communication device. The multi-antenna communication device 500 includes a radio frequency circuit board 510 , wherein the radio frequency circuit board 510 includes, for example, a four-layer circuit board. The RF circuit board 510 further includes a first antenna component 520 and a second antenna component 530 . The first antenna assembly 520 is disposed on the left side of the antenna portion of the first layer circuit board, and the second antenna assembly 530 is disposed on the right side of the antenna portion of the fourth layer circuit board. The arrangement of the first antenna component 520 and the second antenna component 530 can be left-right symmetrical. The radio frequency circuit board 510 is only provided with a plurality of main groun...

Abstract

The invention discloses a multi-antenna communication apparatus, comprising a circuit board having multiple layers of conductors and two antenna assemblies, wherein the antenna assemblies are respectively arranged on the antenna parts on different layers of the circuit board and provided with earth terminals; and the earth terminals are electrically connected to the conductors on the different layers of the circuit board, a current path between the two antenna assemblies is to a main earth through hole of the other layer of circuit board through the earth terminal of one of the two antenna assemblies, and is electrically connected to the earth terminal of the other of the two antenna assemblies.

Description

technical field [0001] The present invention relates to a wireless communication device, in particular to a multi-antenna wireless communication device. Background technique [0002] Traditional wireless communication devices use a single antenna at the transmitting end to transmit electromagnetic waves to transmit signals, and at the receiving end also use a single antenna to receive signals carried by the electromagnetic waves. However, with the evolution of communication algorithms and the progress of integrated circuit manufacturing methods, wireless communication devices are no longer limited to using a single antenna as a component for transmitting and receiving electromagnetic waves. [0003] A multi-input and multi-output (MIMO) wireless communication device uses multiple antennas as components for transmitting and receiving electromagnetic waves. Due to its characteristic of spectral diversity, the MIMO wireless communication device can achieve higher transmission ...
