摘要： In some implementations, an electronics system includes a voltage regulator circuit of a PDN configured to generate a power signal, a printed circuit board (PCB) comprising a power rail to deliver the power signal to a digital circuit generating an interfering signal. The PDN radiating the interfering signal or its harmonics impacting the functionality of destination antenna and circuits (such as Wi-Fi, Bluetooth, cellular, etc.). The system includes a filtering element configured to filter an interfering signal generated by the digital circuit. The filtering element includes a first set of low impedance (low-Z) segments and a second set of high impedance (high-Z) segments. The low-Z and high-Z segments are formed using a copper trace of the power rail and are serially connected to each other. The filtering element forms a low pass filter and filters out high frequency interfering signal going to the destination antenna and circuits by radiated means.

Each support member includes an annular plate mounted on a surface thereof. A first conductive side channel and a second conductive side channel are formed in the side surface and extend along a top-to-bottom dimension of the body. A first set of the annular plates electrically contact the first conductive side channel but not the second conductive side channel and a second set of the annular plates electrically contact the second conductive side channel but not the first conductive side channel. A third conductive side channel is formed in the side surface, extends along the top-to-bottom dimension of the body and is electrically separated from the annular plates.
