Abstract

The invention provides a packaged antenna module and a preparation method thereof, the packaged antenna module comprises a rewiring layer, an antenna structure, a semiconductor chip, a third packaginglayer and a packaged antenna connector, the antenna structure comprises a connector window, and a first antenna structure and a second antenna structure at least stacked on a second surface of the rewiring layer, the packaged antenna connector is located in the connector window and electrically connected with the redistribution layer. According to the invention, the electrical leading-out is carried out through the packaging antenna connector located in the connector window, the signal loss can be reduced, a metal protruding block electrically connected with the rewiring layer does not need to be prepared, electrical connection does not need to be carried out through a flip-chip technology, and therefore, the flexibility of position layout of the packaging antenna module can be improved,and the overall competitive advantage of the WLP AiP is further improved.

Description

technical field [0001] The invention belongs to the technical field of semiconductor packaging, and relates to a packaging antenna module and a preparation method thereof. Background technique [0002] With the popularity of high-tech electronic products, especially in order to meet the needs of mobile, most high-tech electronic products have added the function of wireless communication. [0003] Antenna in Package (AiP for short) is a technology that integrates antennas and chips into packages based on packaging materials and processes to realize system-level wireless functions. Its advantages are: simplified system design, product miniaturization, and low cost . As AiP technology conforms to the trend of increasing integration of silicon-based semiconductor processes, it provides a good antenna and packaging solution for system-level wireless chips. A must-select technology for radar chips, so AiP technology has received extensive attention. [0004] In traditional AiP ...
