Abstract

Aspects of the present disclosure relate to a racetrack that forms part of an RF isolation structure of a packaged module and wireless devices that include such a packaged module. The racetrack can be disposed in a substrate and around an RF component that is on the substrate. The racetrack can include at least one break and/or at least one narrowed section without significantly degrading the EMI performance of the RF isolation structure.
