Asymmetric Patch Antenna Layout for Dense 5G Element Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices face challenges in maintaining effective radiation performance and throughput due to the need for a large number of antenna elements, which are typically designed with symmetry structures that require specific intervals, leading to increased device volume and potential deterioration in radiation performance when these intervals are reduced.
Innovation Solution
The use of asymmetry antenna elements arranged at narrower intervals than the conventional reference interval, allowing for a greater number of elements to be mounted while improving radiation performance and reducing production costs through a simpler manufacturing process.

1Quantity of substance
If symmetry antenna elements are used, then manufacturing is simpler, but the interval between elements must be larger, reducing the number of elements that can be mounted
Solution Approach 1:
The patent applies asymmetry by designing antenna elements with non-uniform geometric structures, specifically using different dimensions in orthogonal directions (e.g., different lengths in x and y directions). This asymmetric design allows the antenna elements to be positioned at narrower intervals while maintaining radiation performance, thereby increasing the number of elements that can be mounted in a given space.
2Volume of stationary object
If antenna elements are spaced at reference interval, then radiation performance is maintained, but device volume increases
Solution Approach 1:
The asymmetric geometric structure of the antenna elements enables them to achieve optimal radiation characteristics at narrower spacing intervals. This allows the device to maintain high radiation performance while reducing the overall volume required for the antenna array, as elements can be packed more densely without compromising performance.
3Adaptability or versatility
If more antenna elements are mounted, then beamforming capability improves, but manufacturing complexity increases
Solution Approach 1:
The asymmetric antenna element design provides consistent radiation characteristics that simplify the beamforming calculation process. By using elements with known asymmetric geometric properties, the system can achieve improved beamforming capability through more elements while maintaining manageable manufacturing complexity, as the asymmetric structure itself becomes a predictable design parameter rather than a source of variability.
