Solution Overview
Problem
The increasing demand for 5G multi-input and multi-output (MIMO) communications and the need for more frequency bands lead to a higher complexity and cost in antenna designs due to the requirement for multiple millimeter-wave and non-millimeter-wave antennas, which results in larger device sizes and reduced product competitiveness.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate 5G non-millimeter-wave antennas and millimeter-wave antenna modules are used to meet 5G MIMO communication requirements, then the communication performance and frequency band coverage are improved, but the device size increases and product competitiveness declines
Solution Approach 1:
The patent combines millimeter-wave antenna modules and non-millimeter-wave antennas into a single integrated antenna module. The module carrier integrates multiple antenna types (millimeter-wave antenna arrays and non-millimeter-wave patch antennas) that can previously only be implemented as separate components, thereby reducing device size while maintaining 5G frequency band coverage capability
Solution Approach 2:
The patent utilizes the height dimension (z-axis) by setting the radio frequency integrated circuit and non-millimeter-wave antennas in non-parallel spaces. This three-dimensional spatial arrangement allows efficient use of vertical space, enabling compact integration without increasing the horizontal footprint of the device
2Adaptability or versatility
If the number of antennas is increased to meet 5G MIMO communication requirements, then the communication performance is improved, but the antenna design complexity and cost increase
Solution Approach 1:
The module carrier serves multiple functions: it acts as the structural support for millimeter-wave antenna arrays, provides the substrate for non-millimeter-wave patch antennas, and serves as the mounting platform for the radio frequency integrated circuit. This multi-functional integration simplifies the overall antenna system design while supporting MIMO communication requirements
Solution Approach 2:
The patent segments the antenna system into distinct functional components (millimeter-wave antenna arrays, non-millimeter-wave patch antennas, and radio frequency integrated circuit) that are independently designed and then integrated on the module carrier. This segmentation allows each component to be optimized separately while maintaining overall system simplicity
3Reliability
If separate antenna designs are used for millimeter-wave and non-millimeter-wave bands, then the antenna performance for each band is optimized, but the overall device size increases
Solution Approach 1:
The patent merges millimeter-wave antenna arrays and non-millimeter-wave patch antennas into a single integrated module on the module carrier. Both antenna types maintain their respective performance optimizations while sharing the same structural platform, eliminating the need for separate antenna assemblies and reducing overall device size
