ABSTRACT:
A combined antenna and electromagnetic shield include a dielectric body mountable to a printed circuit board (PCB), antenna metallization disposed on a first side of the dielectric body and shield metallization disposed on a second side of the dielectric body. The shield metallization serves both as a ground plane for the antenna metallization and as an electromagnetic interference shield for circuit and components on the PCB below. Physical parameters of the component, such as thickness and composition, can be designed to tailor the performance of the antenna formed by the device. Antenna height can be defined by an injection mold, which dramatically reduces variability in the performance of production antennas.
