Comments on "Calculation of the radiation resistance of loop antennas with sinusoidal current distribution"

Richtscheid's paper (see ibid., vol.24, p.889-891, Nov. 1976) used the far zone Poynting power to determine the radiation resistance. The same calculation has been carried out using the conventional induced EMF method (see Sci. Rep. RITU B, vol.9, p.9-10 (1957) and p.79-103, similarly Electrons and Communications in Japan, vol.52-B, p.73-80 (1969))
