Abstract
This paper develops a generalized vector magnetic potential integral formulation
for the paraboloidal reflector antenna, using the elliptic paraboloid geometry as basis. First, parametric expressions informed by the problem geometry are specified for the conventional 'field' and 'source' points, and the ellipse's major and minor axes are described by a common expression, also based on the geometry. When the expressions are utilized in the integral equation for the vector magnetic potential for the problem, and following the usual 'magnitude' and 'phase' approximations, an expression for the radiation field,which may be described as a general expression for certain special cases, emerges. It is shown for example, that when the ellipse's
eccentricity is set to zero to prescribe the circular paraboloid, the corresponding expression for the radiation agrees with those available in the open literature [1,2].
