Problems solved by technology

However, due to the larger BGA solder balls, the profile of the mmWave module is thicker
And because the mobile device is relatively thin, it is difficult to put it directly into a terminal such as a mobile phone

Abstract

The invention discloses a millimeter wave antenna module packaging structure and a mobile device. The packaging structure comprises a multilayer circuit board and a chip; the multilayer circuit boardcomprises a first circuit board layer and a second circuit board layer which are arranged in a stacked manner, and the chip is arranged between the first circuit board layer and the second circuit board layer; the number of the chips is greater than two, and an electromagnetic band gap is arranged between two adjacent chips. According to the invention, the thickness of the section of the millimeter wave module can be reduced, and the isolation between chips can be improved.

Description

technical field [0001] The invention relates to the technical field of antenna module packaging, in particular to a packaging structure of a millimeter wave antenna module and a mobile device. Background technique [0002] With the improvement of integrated circuit technology level, monolithic microwave integrated circuits are more and more widely used, especially the popularization of 5G millimeter wave, hand-held mobile terminals and base stations are widely used in millimeter wave power amplifiers, low noise amplifiers, direction shifters and RF chips such as mixers, in addition to power management (analog chips), digital chips such as FPGAs and single-chip microcomputers used for electromagnetic beam control. For the stable operation of various chips without interfering with each other, improving chip isolation is a problem to be solved. [0003] At the same time, for mobile 5G mmWave modules, the industry chooses to use the combination of RF chips and substrate antenna...
