SYSTEM AND METHOD FOR GROUND FENCING

This abstract first appeared for US patent application 20250149782 titled 'SYSTEM AND METHOD FOR GROUND FENCING

Original Abstract Submitted

techniques to reduce signal interference between wired signals communicated within an electronic device and wireless signals transmitted to or received from antennas of the electronic device are disclosed. the electronic device includes an interposer with an inner fence and an outer fence having offset gaps to prevent a pathway otherwise formed by overlapping tabs, where the pathway allows noise leakage from the wired signals. in some embodiments, the electronic device (e.g., in a main logic board package) includes a ground fencing of ground vias to prevent the noise leakage from harmonics associated with signal vias communicating the wired signals. the spacing between the ground vias is based on frequencies of signals that the ground vias are intended to block.
