Solution Overview
Problem
Conventional wireless communication devices face challenges in miniaturization and space constraints for 5G antenna components, as well as inefficient electrical communication with internal components due to limited antenna placement and complex packaging structures.
Innovation Solution
A packaging structure and method that integrates an antenna module with a carrier, electronic components, and a connector, where the connector's port is exposed from the packaging layer, allowing direct electrical connection to a motherboard and enabling flexible antenna placement for improved signal strength, while simplifying the fabrication process and reducing packaging volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the antenna component is positioned in proximity to the housing to maximize signal strength, then the wireless transmission performance is improved, but the available space for placing the antenna component is limited and the device miniaturization becomes difficult
Solution Approach 1:
The antenna component is integrated with the circuit board to form a unified structure. The antenna component includes a first circuit board and a second circuit board connected through connection portions, creating a compact merged assembly that reduces overall device volume while maintaining signal strength through optimized proximity to the housing.
Solution Approach 2:
The antenna component utilizes three-dimensional spatial arrangement with connection portions extending in multiple directions. The first and second circuit boards are positioned at different heights and connected through vertical and horizontal connection portions, effectively utilizing vertical space to reduce the device's horizontal footprint.
2Reliability
If the antenna component is positioned near the housing, then signal strength is maximized, but the electrical communication with internal components disposed in the center becomes complex
Solution Approach 1:
The circuit board serves multiple functions: it acts as the structural base for the antenna component, provides electrical connection pathways through its connection portions, and enables communication between the antenna and internal components. This multi-functional design simplifies the overall electrical communication architecture.
Solution Approach 2:
The connection portions of the circuit board act as intermediaries that bridge the antenna component positioned near the housing with the internal components located in the center. These connection portions provide direct electrical pathways, eliminating the need for complex routing through multiple intermediate components.
3Ease of manufacture
If conventional packaging structures are used, then the fabrication process is complex and the packaging volume is large, but the electrical performance and power efficiency are compromised
Solution Approach 1:
The antenna component is packaged by integrating it directly with the circuit board structure. The connection portions of the circuit board serve as both structural support and electrical connection elements, eliminating the need for separate packaging components and reducing overall packaging volume while improving electrical performance.
