Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing antennas for portable wireless devices that are compact, efficient, and capable of reduced power consumption while maintaining desired operating characteristics within limited space is challenging, especially when integrating with other components like solar cells.
Innovation Solution
A patch antenna with an electrically conductive mesh layer having a perimeter defined by arcuate segments and a cusp, coupled with an antenna feed, is integrated into a substrate, allowing for reduced size and efficient operation, along with a flexible and optically transmissive design that includes a dielectric layer and antenna ground plane for improved performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the antenna size is reduced to fit limited space in portable devices, then device compactness is improved, but antenna performance and radiation characteristics deteriorate
Solution Approach 1:
The antenna is segmented into a mesh layer with multiple conductive elements arranged in a grid pattern. This segmentation allows the antenna to maintain effective radiating surfaces while reducing the overall physical footprint, enabling compact integration into portable devices without sacrificing radiation performance
Solution Approach 2:
The antenna transitions from a traditional planar patch design to a three-dimensional mesh structure that utilizes vertical layering and spatial arrangement of conductive elements. This dimensional transformation enables the antenna to achieve desired radiation characteristics in a reduced volume by distributing current paths across multiple layers and directions
2Use of energy by moving object
If solar cells are integrated to reduce power consumption, then energy efficiency is improved, but optical transmission and antenna functionality deteriorate due to material properties
Solution Approach 1:
The mesh layer is designed with locally optimized conductive elements that provide both antenna functionality and solar cell integration. The mesh structure allows light to pass through the gaps between conductors while maintaining electrical continuity, enabling simultaneous optical transmission for display and power generation for solar cells in specific regions
Solution Approach 2:
The antenna incorporates a composite mesh structure combining conductive materials with optically transparent substrates. This composite design allows the mesh to function as both an antenna element and a support structure for solar cells, enabling light transmission while maintaining electrical conductivity and mechanical integrity
