1Volume of moving object
If traditional UWB antenna designs are used, then antenna performance can be achieved, but the antennas are too large for integration into modern electronic devices using surface-mount technology
Solution Approach 1:
The patent transitions from planar two-dimensional antenna designs to three-dimensional ceramic substrate structures with metallizations on multiple surfaces (top, bottom, and side walls). This dimensional expansion enables compact UWB antenna integration while maintaining performance through vertical space utilization rather than horizontal expansion.
Solution Approach 2:
The antenna design embeds multiple functional elements within a compact ceramic substrate package, including radiating elements, feed lines, and grounding structures nested within the three-dimensional substrate geometry. This nesting approach achieves high integration density suitable for surface-mount technology.
2Measurement precision
If antenna size is reduced for compact devices, then integration is improved, but localization precision and data transmission performance may deteriorate
Solution Approach 1:
The patent employs a dielectric ceramic substrate material that provides high permittivity and low loss characteristics, enabling compact antenna dimensions while maintaining UWB performance. The ceramic composite structure supports precise electromagnetic field confinement necessary for centimeter-level localization accuracy.
Solution Approach 2:
The antenna design implements localized metallization patterns on specific surfaces of the ceramic substrate, with optimized geometries for radiating elements and feed structures. This localized quality approach concentrates electromagnetic energy in specific regions to achieve high localization precision within a compact form factor.
