Abstract
A sensor device is provided for measuring current in an electrical circuit of a PCB, including a coaxial connector mounted on a tab in the PCB having an inner conductor and a concentric outer conductor, where the tab is formed by a gap through the PCB along a portion of a perimeter surrounding the coaxial connector; a sidewall conductor formed on sidewalls of the tab and connected to ground plane; and resistors mounted on the PCB and arranged along the portion of the perimeter surrounding the coaxial connector, each resistor being connected between the inner conductor and the sidewall conductor. Current from the electrical circuit flows in a first direction through the ground plane creating a first magnetic field, and flows in a second direction between the sidewall conductor and the inner conductor through the resistors creating a second magnetic field, where the first and second magnetic field partially cancel.
