Problems solved by technology

Because the metal material will have a shielding effect on the antenna signal, the upper and lower projection areas of the antenna often cannot cover the metal to work normally.
In this way, for wireless routers, it is equivalent to a larger compression of the heat sink area, which is not conducive to heat dissipation, and will also cause the device to often malfunction due to long-term use and excessive temperature.

Abstract

The present invention provides a WiFi dual-band antenna array based on metal heat dissipation plates. The WiFi dual-band antenna array is characterized by comprising: a PCB; a frame which is in a central symmetry shape and is fixed on the PCB; an even number of metal heat dissipation plates which are symmetrically fixed on side edges of the frame, wherein the middle position of each metal heat dissipation plate is provided with a gap; insulating substrates filled in the gaps; an even number of antennas which have one-to-one correspondence with the metal heat dissipation plates and are fixed on the insulating substrates; and an even number of coaxial feeders which have one-to-one correspondence with the antennas and are fixed on the antennas, wherein the distance between the metal heat dissipation plate and the antenna is greater than a predetermined distance.

Description

technical field [0001] The invention relates to the field of wireless communication of household intelligent equipment, in particular to a WiFi dual-band antenna array based on a metal heat dissipation plate. Background technique [0002] With the wide application of mobile communication, especially the requirement for the wireless communication rate of WiFi access is getting higher and higher. Compared with the single-send-single-receive (SISO) system, the multiple-input-output (MIMO) system adopts a multi-antenna solution at the transceiver end, which can greatly increase the channel capacity without increasing the bandwidth. Therefore, introducing a multi-antenna solution into a wireless router has become a mainstream configuration. [0003] In addition, due to the increasing number of wireless terminals connected by wireless routers with 2.4GHz, the phenomenon of mutual interference between devices in each 2.4GHz frequency band is relatively serious, which is often caus...
