The paper presents the evaluation of capacitance matrix of an artificial orbiting satellite considering a composite metallic structure of a parabolic reflector antenna with cuboid and plates. Integral equations are formed by relating the unknown charge density on the metallic conductor and are solved using the Method of Moments (MoM) in which the pulse functions are used as basis functions and the delta functions are used as testing functions. The surfaces of the conducting structure are meshed

The numerical data on the capacitance matrix and charge distribution of these structures have been presented. The capacitance of a metallic cuboid is computed to validate the approach.
