Wireless Circuit Grounding Segmentation for ESD and Signal Loss

The grounding system is segmented into multiple independent grounding line sets (first, second, and third grounding line sets) with different functions. The first grounding line set provides external grounding, the second provides internal grounding, and the third provides both external and internal grounding. This segmentation allows the system to achieve EMS and ESD protection by separating internal and external grounds while maintaining structural organization through clear functional division.

Different grounding line sets are assigned different local qualities and functions. The first grounding line set is optimized for external grounding with specific geometric arrangements, the second for internal grounding, and the third for dual functionality. This local quality differentiation allows each grounding line set to be optimized for its specific purpose, reducing signal loss while maintaining manufacturability through standardized design patterns for each type.

The grounding structure transitions from a traditional single-layer planar configuration to a multi-layer three-dimensional arrangement. The first, second, and third grounding line sets are positioned at different vertical levels and horizontal locations, creating a spatial distribution of grounding paths. This dimensional expansion allows the system to reject electromagnetic interference and radiation more effectively by providing multiple pathways for noise cancellation while maintaining circuit simplicity through systematic arrangement.
