Claim:
1. A magnetic field sensor assembly comprising: four side radio frequency (RF) elements, each side RF element comprising an RF connection; four side RF feed cables operably connected to one of the four side RF elements such that each side RF element is connected to one RF feed cable that provides a feed signal to the side RF element; a top RF element; a top RF element feed cable that provides a top RF feed signal to the top RF element; a bottom RF element; a bottom RF element feed cable that provides a bottom RF feed signal to the bottom RF element, wherein the four side RF side elements, the top RF element, and the bottom RF element are arranged in a cube formation; and a nitrogen-vacancy (NV) center diamond located within the cube formation, wherein the side RF elements, top RF element, and bottom RF element generate a microwave signal that is uniform over the NV center diamond, and wherein the side RF elements, top RF element, and bottom RF element generate a magnetic bias field to the NV center diamond.
