Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing an antenna module for mobile terminals that simultaneously supports existing 4G frequency bands and is compatible with sub-6 GHz frequency bands to enhance communication performance is a pressing challenge in the 5G era.
Innovation Solution
The antenna module is designed with distinct groups of antennas arranged on opposite sides of the housing, including 4G and 5G frequency band antennas, forming a 4*4MIMO antenna group, allowing for compatibility with sub-6 GHz frequencies without affecting 4G performance. The first and second antenna groups operate in 4G and 5G bands respectively, while the third and fourth groups, along with additional antennas, operate in 5G, forming a 4*4MIMO configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna module includes multiple antenna groups arranged on opposite sides of the housing to support both 4G and 5G frequency bands, then the communication performance and frequency band compatibility are improved, but the device complexity increases
Solution Approach 1:
The antenna module is divided into four distinct antenna groups (first, second, third, and fourth antenna groups), each configured to operate in specific frequency bands. The first and third antenna groups are arranged on opposite sides in a first direction, while the second and fourth antenna groups are arranged on opposite sides in a second direction perpendicular to the first direction. This segmentation allows each group to be optimized for specific 4G or 5G frequency bands, improving overall frequency band compatibility while maintaining manageable complexity through modular organization.
Solution Approach 2:
The patent utilizes spatial arrangement in multiple dimensions by positioning antenna groups on opposite sides of the housing in two perpendicular directions. This three-dimensional spatial distribution enables the antenna module to support both 4G and 5G frequency bands simultaneously without requiring all antennas to be placed in a single plane, thereby improving frequency band adaptability while efficiently utilizing the available space within the housing.
2Reliability
If the third, fourth, sixth, and seventh antennas form a 4*4MIMO antenna group for 5G operation, then the 5G communication performance is improved, but the arrangement complexity and space requirements increase
Solution Approach 1:
The antenna module segments the 5G MIMO functionality into the second and fourth antenna groups, each containing two antennas (third and fourth antennas in the second group, sixth and seventh antennas in the fourth group). These groups are arranged on opposite sides of the housing in the second direction, creating a distributed 4*4MIMO configuration that achieves high reliability 5G communication while distributing the physical arrangement across different spatial locations, thereby managing complexity through spatial segmentation.
Solution Approach 2:
The antenna groups are designed with multi-functionality to serve both 4G and 5G communication requirements. The second and fourth antenna groups, which form part of the 4*4MIMO configuration for 5G, are also configured to operate in 4G frequency bands. This universal design allows the same antenna structures to fulfill multiple functions across different frequency bands, improving communication performance without proportionally increasing arrangement complexity.
