Solution Overview
Problem
Existing 5G antenna technologies occupy a larger volume due to the separate design of non-millimeter wave and millimeter wave antennas, leading to inefficient space utilization in electronic devices.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If non-millimeter wave antenna and millimeter wave antenna are designed separately, then each antenna can be optimized for its specific frequency band, but the overall volume occupied by antennas increases
Solution Approach 1:
The patent combines non-millimeter wave antenna and millimeter wave antenna into a single integrated antenna module. The substrate integrates multiple antenna elements including dipole antenna units for millimeter wave communication and other antenna structures for non-millimeter wave frequencies, allowing both antenna types to coexist in a compact unified structure rather than separate designs
Solution Approach 2:
The patent utilizes three-dimensional space arrangement by stacking antenna elements on different layers of the substrate. The dipole antenna units are arranged in specific patterns across multiple layers, and the reflector structure extends in the vertical dimension, effectively using spatial dimensionality to pack multiple antenna functions into a smaller overall volume
2Reliability
If dipole antenna units are arranged with intervals along the substrate, then radiation performance is improved, but the area occupied increases
Solution Approach 1:
The patent transitions from two-dimensional planar arrangement to three-dimensional layered configuration. Dipole antenna units are distributed across multiple substrate layers with vertical spacing, allowing radiation performance optimization through proper spacing while maintaining a compact overall footprint by utilizing the vertical dimension rather than expanding horizontally
