Abstract

Aspects of the present disclosure relate to determining a layout of a racetrack that forms part of an RF isolation structure of a packaged module and the resulting RF isolation structures. The racetrack layout can be determined based on identifying low radiating areas of a module and/or areas of a module that are less sensitive to external radiation. The racetrack can be disposed below a surface of a module on which a radio frequency component is disposed. The racetrack and a conductive layer over the radio frequency component can form part of a radio frequency isolation structure around the RF component.
