SYSTEM AND METHOD FOR GROUND FENCING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17738787 titled 'SYSTEM AND METHOD FOR GROUND FENCING
Simplified Explanation
- The patent application discusses techniques to reduce signal interference between wired signals and wireless signals in an electronic device. - The electronic device includes an interposer with an inner fence and an outer fence that have offset gaps to prevent noise leakage from the wired signals. - The offset gaps prevent the formation of a pathway created by overlapping tabs, which would allow noise to leak from the wired signals. - In some embodiments, the electronic device includes a ground fencing of ground vias to prevent noise leakage from harmonics associated with signal vias. - The spacing between the ground vias is determined based on the frequencies of the signals that the ground vias are intended to block.
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.
