Electronic equipment integrated with millimeter wave array antenna

Abstract

The invention discloses electronic equipment integrated with a millimeter wave array antenna. The millimeter wave antenna comprises a millimeter wave antenna array, a main printed circuit board (PCB),a battery and a first metal middle frame, the method is characterized in that the first metal middle frame comprises a metal frame positioned on the appearance surface of the electronic equipment anda large-area metal block for supporting and grounding; the metal frames comprise a metal frame I, a metal frame II, a metal frame III and a metal frame IV; a first double-sided groove area is arranged in the metal frame I, grooves are formed in the front surface and the back surface of the first double-sided groove area, a metal partition is arranged in the middle of the first double-sided groovearea, the first groove area is used for arranging a millimeter wave antenna array, and the millimeter wave antenna array consists of more than two antenna units and is arranged in an array form. According to the invention, the optimal radiation direction of the millimeter wave array antenna can be realized, performance degradation caused by shielding of the millimeter wave array antenna by surrounding devices or the environment when consumers use the millimeter wave array antenna is avoided, the feeding and grounding realization mode is simple, and the realization cost is low.

Description

Technical field [0001] The invention relates to the field of mobile communication, and in particular to an electronic device integrating a millimeter wave array antenna. Background technique [0002] At present, commercial 5G (fifth generation mobile communications) will be implemented around 2020, including the Sub 6GHz frequency band and millimeter wave (millimeter wave) frequency band. Millimeter wave refers to electromagnetic waves with a wavelength of millimeter level and a frequency of 30 to 300 GHz. It has the advantages of large bandwidth and large channel capacity, and can better meet the needs of 5G communications for large data traffic. At present, the research and development of phased array beamforming in the 5G sub-6Ghz MIMO technology and millimeter wave frequency band in smart terminal equipment has attracted people's attention. [0003] In the terminal equipment, the conventional millimeter wave antenna integrates the radiating element directly into the back end o...

Problems solved by technology

[0003] In the terminal equipment, the conventional millimeter wave antenna directly integrates the radiating element into the back end of the RF chip stack, integrates with the chip, and sets it on the main printed circuit board (PCB), but its radiation direction can only be towards the back of the terminal equipment. , easily occluded

If it is placed upright around the terminal equipment, the problem of antenna radiation directionality will be improved, but how the millimeter wave antenna coexists with 2G, 3G, 4G antennas, and how to coexist with the metalized body will bring challenges to engineering design
