Abstract
A high gain multimode dielectric coated rectangular horn antenna operating in two orthogonal 
and 
+ TE/_{TM21} mode sets to generate a circularly polarised elliptical shaped beam is described. The radiation characteristics together with the on-axis gain of the antenna are derived from electric vector-potential on the basis of vector diffraction formula. This antenna which can be used in conjunction with spacecraft (or satellite antenna) to illuminate an elliptical zone on the earth surface will offer better directivity high on axis gain, low side lobes, less R.F. sensitivity to shape environment and low cost.
