Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The radiation performance of millimeter-wave antennas is relatively low in existing technologies, limiting communication speed, latency, and simultaneous connections.
Innovation Solution
The antenna design includes a plate body with a groove, a coupling frame body, four radiators, and four couplers, where the radiators and couplers are disposed in a space enclosed by the coupling frame body, with electric conductors connecting to feed points, and an insulating medium filling the space between them, enabling dual polarization and resonant frequencies, improving radiation performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional millimeter-wave antenna designs are used, then the device structure is simple, but the radiation performance is low
Solution Approach 1:
The antenna is divided into multiple independent radiating elements (first radiator, second radiator, third radiator, fourth radiator) with distinct feed points and coupling structures. Each radiator is independently fed through separate electric conductors, allowing individual optimization of radiation patterns and polarization characteristics while maintaining overall system performance
Solution Approach 2:
The coupling frame body is disposed within a groove formed in the plate body, creating a nested structure where the coupling frame body and radiators are contained within the plate body's groove. This nested arrangement reduces overall antenna profile while maintaining radiation performance
2Reliability
If more array units are used to meet 3GPP requirements, then the radiation performance improves, but the array dimensions increase
Solution Approach 1:
The antenna design utilizes three-dimensional spatial arrangement of radiators and coupling structures. The coupling frame body extends in multiple dimensions within the groove, allowing radiators to be positioned at different heights and lateral positions. This 3D configuration achieves required radiation performance without increasing the planar footprint of the antenna array
3Volume of moving object
If radiators and couplers are placed close together to reduce size, then the device compactness improves, but contact between components may occur causing performance degradation
Solution Approach 1:
An insulating medium is introduced between the plate body, coupling frame body, radiators, and couplers to prevent unwanted contact and electrical interference. This intermediary material maintains precise spacing between components while allowing them to be positioned close together for compactness, ensuring both size reduction and performance reliability
