%X A formula of input impedance of a circular loop antenna in spherical cavity surrounding by conductive medium is obtained. The definition of radiation performance of the antenna in conductive medium is given. The formula of radiation resistance of the antenna is derived. The results of numerical calculation show that the two formulas converge very fast, so it is feasibe to take the first term or the sum of first two terms only. The relationship between above mentioned characteristics and the parameters, such as the radius of spherical cavity and others, is discussed.
