Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of small cells for 5G network densification in urban areas is hindered by challenges such as finding suitable locations, high costs of outdoor fiber and electricity installation, and urbanistic regulations, while existing planar antennas integrated into building facades face complications in electrical connection, maintenance, and limited frequency band optimization due to component thickness constraints.
Innovation Solution
A transparent antenna system inscribed in a parallelepiped with a transparent dielectric panel configuration, featuring a patch network, feeding network, and ground plane, where the ground plane is located between the feeding network and the second transparent dielectric panel, allowing for adjustable distances and configurations to optimize transmission and reception, enabling seamless indoor or outdoor placement without impairing urban aesthetics.

Engineering Contradiction Analysis
1Object-affected harmful factors
If planar antennas are integrated into building facades, then urban aesthetics are preserved and outdoor installation challenges are reduced, but electrical connection, installation, and maintenance become complicated and impossible to manage
Solution Approach 1:
The antenna system is divided into separate modular components: the transparent antenna arrangement can be installed independently on the facade, while electrical connections are made through accessible interfaces. This segmentation allows the aesthetic integration of the antenna into the building facade while maintaining separate, manageable access points for installation and maintenance operations.
Solution Approach 2:
The patent introduces intermediate structures such as mounting frames and connection interfaces that mediate between the antenna elements and the building facade. These intermediaries provide accessible pathways for electrical connections and maintenance access while allowing the antenna to be visually integrated into the facade structure.
2Productivity
If antennas are installed in dense urban areas for 5G capacity improvement, then network capacity is improved, but finding suitable locations and complying with urbanistic regulations becomes difficult
Solution Approach 1:
The transparent antenna arrangement is designed to serve multiple functions: it provides 5G communication capacity while simultaneously maintaining building aesthetic requirements. The same antenna structure can be deployed on various building surfaces (facades, windows, glass structures) without requiring specific architectural features, making it universally adaptable to different urban environments and building types.
Solution Approach 2:
The use of transparent or translucent materials for the antenna housing and elements allows the antenna to visually blend with the building facade. This optical property enables the antenna to be deployed in aesthetically sensitive urban areas where traditional antennas would be visible and unacceptable, thereby expanding deployment location flexibility.
3Reliability
If the ground plane is positioned between the feeding network and the second transparent dielectric panel, then transmission and reception performance is optimized, but the structural complexity increases
Solution Approach 1:
The ground plane is integrated directly into the second transparent dielectric panel structure, combining the ground plane function with the structural panel. This merging approach achieves the required electromagnetic performance with minimal additional structural complexity, as the ground plane becomes part of the existing transparent panel rather than a separate component.
Solution Approach 2:
The patent optimizes transmission and reception by adjusting the position of the ground plane relative to the feeding network and dielectric panels. By changing the spatial parameter (distance and positioning) of the ground plane, the system achieves optimal electromagnetic performance without requiring complex structural modifications.
