Distributed-MIMO Antenna Layout for High-Throughput Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed-MIMO wireless communication, securing an installation place that forms a communication area with relatively high throughput is difficult due to the requirement for antenna units to be installed at a certain distance from each other, and the limited propagation of high-frequency radio waves like microwaves.
Innovation Solution
The antenna set includes a group of antenna units installed at a height between 3 m and 8 m with a non-directional radiation pattern of 180° or more in the horizontal plane and a radiation peak inclined at a depression angle of 0° to 15°, allowing for expanded communication areas with high throughput by overlapping beams and minimizing interference from obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If antenna units are installed at a certain distance from each other for distributed-MIMO, then stream transmission capability is improved, but installation place availability deteriorates
Solution Approach 1:
The patent transitions from horizontal distribution to vertical distribution by installing antenna units at different heights (3m-8m) on the same pole structure. This dimensional change allows distributed-MIMO functionality to be achieved without requiring large horizontal separation distances, thereby resolving the contradiction between stream transmission capability and installation place availability.
2Area of stationary object
If antenna units are installed at heights of 3m-8m, then communication area coverage is improved, but installation complexity increases
Solution Approach 1:
The pole structure is designed to serve multiple functions: it simultaneously supports mounting of multiple antenna units at different heights, provides structural stability for vertical distribution, and enables simplified installation compared to horizontal distribution requiring multiple separate locations. This multi-functionality resolves the contradiction between expanded communication area coverage and installation complexity.
3Productivity
If radiation peak is inclined at depression angle of 0°-15°, then throughput in communication area is improved, but radiation coverage area decreases
Solution Approach 1:
The radiation pattern is optimized with a depression angle of 0°-15° to concentrate energy in the specific direction of the communication area, improving throughput locally. The vertical distribution of antenna units at different heights compensates for the reduced overall coverage area by creating overlapping radiation patterns that collectively cover the required service area, thus resolving the contradiction between localized throughput improvement and overall coverage area.

Function Achieved in This Case
This configuration enables the formation of a communication area with relatively high throughput by enhancing gain and coverage, even in the presence of obstacles, by optimizing installation height and beam inclination.
