Solution Overview
Problem
The integration of millimeter-wave antennas in terminal devices requires additional space, leading to increased size and reduced competitiveness due to the need for separate accommodating spaces.
Innovation Solution
A terminal device design featuring a metal frame with grooves for coupling and radiating patches, where the metal frame is grounded, and non-conductive material is used to fill the gaps, allowing for a millimeter-wave array antenna integration without increasing the device's size, while maintaining a metal appearance and supporting multiple-input multiple-output functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an independent antenna module is used for millimeter-wave antenna, then the antenna functionality is achieved, but the terminal device size increases
Solution Approach 1:
The patent merges the millimeter-wave antenna with the existing metal frame structure of the terminal device. The metal frame is designed with grooves that directly accommodate the antenna elements, eliminating the need for a separate independent antenna module. This integration allows the antenna functionality to be achieved while avoiding additional space occupation, thus resolving the contradiction between antenna functionality and device size.
Solution Approach 2:
The metal frame serves dual functions: it provides the structural support for the terminal device and simultaneously acts as the housing for the millimeter-wave antenna elements. The grooves in the metal frame are specifically designed to hold the antenna elements, making the frame a multi-functional component that reduces overall device complexity and size while maintaining antenna performance.
2Volume of moving object
If the metal frame is used as part of the antenna structure, then the device size is reduced, but the manufacturing complexity increases
Solution Approach 1:
The antenna structure is segmented into discrete elements that are placed within the grooves of the metal frame. Each antenna element can be manufactured separately and then positioned within the predefined grooves, simplifying the overall manufacturing process. This segmentation allows for modular assembly, reducing the complexity of manufacturing the integrated structure compared to creating a fully custom integrated design.
Solution Approach 2:
The grooves in the metal frame act as intermediaries that facilitate the integration of antenna elements. These grooves provide predefined positioning and support structures that simplify the assembly process. By incorporating these intermediary features into the metal frame design, the patent reduces manufacturing complexity while maintaining the space-saving integrated structure.
