Compact Antenna Assembly Layout for Multi-Band Smartphone Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna devices are too large to be mounted in smartphones, requiring manufacturers to adjust their size to fit the inner space of the device, which wastes time and increases manufacturing costs.
Innovation Solution
The electronic device and antenna assembly feature a compact design with a substrate and three antenna components arranged sequentially, including radiation and ground portions with notch and slit sections, allowing for reduced size without compromising signal frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna device is designed to cover various signal frequency bands, then the range of applicable signal frequency bands is improved, but the size of the antenna device increases making it difficult to mount in smartphones
Solution Approach 1:
The antenna device is divided into three separate antenna components (first, second, and third antenna components), each capable of operating in different signal frequency bands. These segmented components are arranged along an arrangement direction on a substrate, allowing the antenna device to cover multiple frequency bands while keeping each individual component compact in size.
Solution Approach 2:
The antenna components are arranged in a linear sequence along an arrangement direction rather than being distributed in a two-dimensional plane. This one-dimensional arrangement optimizes space utilization and reduces the overall area occupied by the antenna device while maintaining the capability to support multiple frequency bands.
2Area of stationary object
If the size of the antenna device is reduced to fit smartphone inner space, then the ease of mounting is improved, but the range of applicable signal frequency bands may be reduced
Solution Approach 1:
Multiple antenna components that would traditionally require separate mounting locations are merged onto a single substrate and integrated into one antenna device. This consolidation reduces the overall space required while maintaining the combined frequency band coverage of all individual components, allowing the antenna device to fit within smartphone inner space without sacrificing frequency band adaptability.
3Area of stationary object
If manufacturers adjust the size of the antenna device to fit smartphone inner space, then the ease of mounting is improved, but the design time and manufacturing costs increase
Solution Approach 1:
The antenna device is designed with a universal structure that can be directly mounted in various smartphone models without requiring manufacturer-specific size adjustments. The three antenna components are integrated in a compact arrangement that fits standard smartphone inner spaces, eliminating the need for custom design modifications and reducing both design time and manufacturing costs.
