Solution Overview
Problem
Existing millimeter-wave antennas occupy too much space in wireless communication terminals, degrading performance and increasing the overall volume of the system, which affects product competitiveness.
Innovation Solution
An antenna structure is integrated into a metal plate with accommodating grooves, where radiation and coupling pieces are disposed, and a radio frequency module is connected to the radiation piece, increasing bandwidth and reducing space occupancy, while allowing for multiple input multiple output (MIMO) functionality and improved wireless diversity connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If millimeter-wave antennas are integrated into mobile terminals, then wireless communication performance is improved, but antenna space occupancy increases
Solution Approach 1:
The patent embeds the antenna structure within grooves formed on the metal plate surface, nesting the radiation element and coupling element into the metal plate itself. This integration reduces the external space required while maintaining antenna functionality for millimeter-wave communication.
Solution Approach 2:
The patent combines the antenna structure with the metal plate by forming grooves directly on the metal plate and integrating the radiation and coupling elements within these grooves. This merging eliminates separate antenna components and reduces overall space occupancy while improving wireless communication performance.
2Ease of manufacture
If antenna elements are discretely disposed, then manufacturing is simplified, but available space is squeezed and performance degrades
Solution Approach 1:
The patent merges the radiation element and coupling element into a single integrated antenna structure formed on the metal plate. This integration maintains manufacturing simplicity while eliminating the space squeezing and performance degradation caused by discrete disposal of antenna elements.
Solution Approach 2:
The patent nests both antenna elements within grooves formed on the metal plate surface, creating a compact integrated structure that simplifies manufacturing while preserving adequate space for optimal antenna performance.
3Area of stationary object
If antenna structure is integrated into metal plate with grooves, then space occupancy is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent segments the metal plate surface by forming grooves that divide the surface into distinct regions for the radiation element and coupling element. This segmentation achieves space reduction while maintaining relatively simple manufacturing processes through standard groove formation techniques.
4Reliability
If radiation piece and coupling piece are insulated from metal plate, then antenna performance is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent nests the radiation piece and coupling piece within grooves formed on the metal plate, providing natural mechanical support and positioning. The groove structure inherently maintains the required insulation and positioning accuracy, reducing the need for additional precision manufacturing measures.
