Abstract:
1. A wireless device comprising: an antenna configured to facilitate at least one of transmitting or receiving a radio-frequency (RF) signal; a packaged module in communication with the antenna, the packaged module including a ground contact configured to receive a ground potential; a plurality of vias in a substrate, the plurality of vias disposed along a periphery of the packaged module, and vias of the plurality of vias being spaced closer together along the periphery of the packaged module in a hot spot than in a low radiating area; a conductive trace disposed along the periphery of the substrate and in a different layer of the substrate than the plurality of vias; an RF circuit coupled to a major surface of the substrate; and a conductive layer disposed over the RF circuit, the conductive layer electrically coupled to the plurality of vias and the ground contact such that the plurality of vias and the conductive layer form at least a portion of an RF isolation structure around the RF circuit, and the conductive trace being included in an electrical connection between the conductive layer and the ground contact; and an other module in communication with the packaged module.
