Abstract
Aspects of the disclosure provide for a system for a power over data line (PoDL) system. The system includes a ground plane that has a cutout. In addition, an alternating current (AC) capacitor pad configured to establish a bidirectional data channel. The AC capacitor pad is positioned in the cutout of the ground plane. Similarly, a PoDL pad connected to one or more inductors and a direct current (DC) power source is positioned in the cutout of the ground plane and is in series with the AC capacitor pad.
