Solar Battery Unit Antenna Layout for Signal Integrity

The patent resolves the contradiction by transitioning from a two-dimensional overlapping layout to a three-dimensional stacked arrangement. The antenna is disposed on the front surface of the substrate while the solar battery is positioned on the back surface, utilizing the vertical dimension to eliminate spatial overlap. This dimensional separation prevents the solar battery from attenuating radio waves while maintaining structural compactness, as both components occupy the same footprint area without interfering with each other's functionality.

The patent applies dimensional separation by placing the antenna and solar battery on opposite surfaces of the substrate (front and back faces respectively). This allows both components to maintain their optimal positions without requiring increased lateral separation, thereby preserving communication performance while minimizing the overall device footprint. The vertical stacking approach enables compact integration without compromising functional performance.
