Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for integrating multiple frequency bands into portable electronic devices poses a challenge due to limited antenna space, as conventional antenna designs struggle to accommodate additional frequency bands within the restricted size of these devices.
Innovation Solution
The use of multiple carrier blocks with varying 3D shapes, coupled in a way to increase the overall surface area, allowing radiators to be routed on multiple surfaces, thereby efficiently utilizing the limited antenna space and incorporating more frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional antenna designs are used, then the antenna structure is simple, but the number of frequency bands that can be integrated is limited due to restricted antenna space
Solution Approach 1:
The patent transitions from planar 2D antenna carrier to three-dimensional 3D antenna carrier structure. The 3D carrier includes multiple surfaces (top surface, bottom surface, and side surfaces) that can accommodate radiating elements, effectively increasing the antenna space from two dimensions to three dimensions. This dimensional change allows integration of multiple frequency bands without increasing the overall device volume.
Solution Approach 2:
The 3D antenna carrier is divided into multiple segments or sections with different surfaces (top surface, bottom surface, side surfaces). Each surface can independently accommodate radiating elements for different frequency bands. This segmentation allows flexible arrangement of multiple antennas on different surfaces, enabling integration of multiple frequency bands while maintaining compact form factor.
2Adaptability or versatility
If multiple frequency bands are integrated into a single device, then the functionality increases, but the available antenna space decreases
Solution Approach 1:
The patent utilizes three-dimensional space by creating a 3D antenna carrier with multiple surfaces (top, bottom, and side surfaces). This allows radiating elements for multiple frequency bands to be arranged on different surfaces, effectively increasing the antenna area without increasing the device footprint. The vertical and lateral surfaces provide additional mounting areas that would not be available in conventional planar designs.
Solution Approach 2:
The 3D antenna carrier serves multiple functions: it provides mounting surfaces for radiating elements on all its surfaces (top, bottom, side), acts as a structural support, and enables integration of multiple frequency bands. The carrier structure itself becomes a multi-functional element that accommodates different antenna configurations for various functionalities (cellular, Wi-Fi, Bluetooth, GPS) within the same device volume.
