1Volume of moving object
If the device is made thinner and more compact, then the device size is reduced, but the space for antenna modules is reduced leading to poor frequency signal radiation performance
Solution Approach 1:
The patent transitions from traditional planar antenna designs to a three-dimensional substrate integrated waveguide structure with through-holes penetrating multiple layers. This vertical dimensionality change enables compact antenna implementation while maintaining radiation performance by utilizing the Z-axis space within the display device.
Solution Approach 2:
The antenna structure is nested within the display device layers, with through-holes formed in the base layer and lower member layer, and slots defined in the sensor layer and common electrode. This nesting approach integrates the antenna module within the existing device structure without increasing overall device thickness.
2Reliability
If traditional antenna designs are used, then the structure is simple, but the frequency signal radiation performance is poor in thin devices
Solution Approach 1:
The antenna structure utilizes composite construction combining dielectric layers (base layer, sensor layer, common electrode) with conductive elements (through-holes with metal coating, slots in conductive layers). This composite approach enables the waveguide structure to achieve both mechanical integrity and electromagnetic radiation functionality.
Solution Approach 2:
The antenna is segmented into multiple functional components: through-holes in the base and lower member layers, slots in the sensor layer and common electrode, and metal coatings on through-hole surfaces. This segmentation allows each component to be optimized for its specific function while collectively achieving improved radiation performance.
