Abstract

High-speed traces routed in close proximity to a GPS patch antenna in a compact consumer electronic device could cause desensitization of the GPS receiver. Noise coupling mechanisms between the traces and the antenna are studied, together with the field patterns of the patch antenna. The insights gained in the understanding of the underlying coupling physics are further used to develop general trace routing rules for minimizing radio frequency interference in the GPS band.
