      The first mitigation scheme to minimize interference is demonstrated in this video which involves making changes on the PCB itself. The changes primarily include additional shielding in the form of dropping a via fence to protect the electronics, the victim WiFi radio in this case, to better isolate the antenna from electromagnetic interference. Watch the video to see how easy it is to modify a PCB design in HFSS 3D Layout.
