A wrist carried wireless instrument for minimizing the effects of coming in contact with the wrist of the user is provided. A case contains wireless instrument circuitry. A loop antenna extends without the case. An antenna resonance circuit has two capacitors connected in series. The two capacitors are connected to the loop antenna. A connection between two of the capacitors is formed at substantially the half impedance value across the capacitors and is a ground electric potential. An RF amplifier connects the loop antenna to the wireless instrument circuitry.
