1Length of moving object
If electronic devices are designed to be thinner, then the device thickness is reduced and portability is improved, but the available space for mounting antennas is limited
Solution Approach 1:
The patent transitions from conventional planar antenna layouts to a three-dimensional winding structure. The conductive pattern forms multiple turns stacked in the thickness direction, effectively utilizing the Z-axis dimension to increase antenna length and electrical performance without increasing the device's footprint area, thereby resolving the contradiction between thin design and antenna space limitation.
Solution Approach 2:
The conductive pattern is nested within the housing thickness, with multiple turns of the winding portion stacked along the thickness direction. This nesting approach allows the antenna to occupy vertical space rather than horizontal space, enabling effective antenna integration in thin-profile devices with limited planar area.
2Reliability
If conventional multi-layer antenna structures are used, then antenna performance is improved, but fabrication complexity and cost increase
Solution Approach 1:
The patent combines multiple antenna functions and performance characteristics into a single-layer winding structure. By forming the conductive pattern in one layer with multiple turns, the design achieves the electrical performance typically requiring multiple layers, thereby simplifying the overall structure and reducing fabrication complexity while maintaining antenna effectiveness.
Solution Approach 2:
The conductive pattern is segmented into multiple turns or loops within a single layer, each turn contributing to the overall antenna performance. This segmentation allows the antenna to achieve complex electromagnetic characteristics without requiring multiple physical layers, simplifying the manufacturing process while maintaining functional performance.
