1. A medical probe, comprising:
an insertion tube for insertion into a patient body;
an arm attached to a distal end of the insertion tube, the arm comprising a printed circuit board;
a reference electrode on a surface of the printed circuit board and configured to contact internal tissues, the reference electrode having a first shape; and
exactly three electrodes, each having a second shape different from the first shape, the exactly three electrodes surrounding the reference electrode such that the exactly three electrodes are configured to sense anatomical signals and provide electrical signals which, when measured relative to the reference electrode, are indicative of the anatomical signals in the patient body,
the reference electrode and the exactly three electrodes forming an electrode assembly, with the second shape of the exactly three electrodes being an arcuate shape that is not a circle,
the electrode assembly comprising a center of gravity, and
a center of gravity of the reference electrode aligning with the center of gravity of the electrode assembly.
