Terminal Rear Cover Antenna Array to Prevent Signal Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing terminal designs face limitations where the metal rear cover can shield wireless signals, restricting the antenna module's performance and requiring the rear cover to be made of non-metal material, which can lead to signal energy loss.
Innovation Solution
A terminal housing design with a rear cover that includes a first area with antenna array elements coupled using insulating material, allowing the antenna array to be exposed and directly transmit/receive signals, and the RF module is electrically coupled to each antenna array element, enabling effective signal transmission and reception without signal blocking, and allowing the rear cover to be made of either metal or non-metal material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the rear cover is made of metal material, then the structural strength and aesthetic appearance are improved, but the wireless signal transmission is shielded and antenna performance deteriorates
Solution Approach 1:
The rear cover is segmented into a first area containing antenna array elements and a second area for other components. The antenna array elements are arranged in a matrix structure within the first area, allowing signal transmission while maintaining the overall metal cover structure. This segmentation enables the metal rear cover to coexist with functional antenna elements without complete signal blocking.
Solution Approach 2:
Different areas of the rear cover are assigned different functions: the first area is optimized for antenna signal transmission with specific antenna element arrangements, while the second area maintains the structural and aesthetic properties of the metal cover. This local differentiation allows the metal cover to provide strength and appearance while the antenna area ensures signal transmission.
2Object-affected harmful factors
If the rear cover is made of non-metal material, then signal shielding is avoided and antenna performance is improved, but signal energy loss increases
Solution Approach 1:
The terminal employs a composite structure combining metal rear cover with antenna array elements made of conductive materials. The metal cover provides structural strength and aesthetic appearance, while the antenna elements (made of conductive materials like copper or aluminum) ensure efficient signal transmission. This composite approach leverages the advantages of both metal and non-metal materials, avoiding the drawbacks of using either material alone.
3Object-affected harmful factors
If the antenna array elements are arranged in a matrix structure, then the signal transmission coverage is improved, but the manufacturing complexity increases
Solution Approach 1:
The antenna array is segmented into multiple identical antenna elements arranged in a matrix pattern. Each element has the same structure and function, simplifying the manufacturing process through standardization. The matrix arrangement (e.g., 2x2, 3x3) provides systematic signal coverage while allowing modular assembly and simplified production compared to irregular antenna configurations.
