Abstract
In radioastronomy systems, polarizing grids are widely used for diverse purposes. The paper presents a study of the beam radiated by a conical corrugated horn which couples with an ideal polarizing grid; beam mode expansion, including fundamental and higher order modes, is taken into consideration. Therefore, the accuracy of the analysis is improved. A study of transmitted beams as functions of grid wires angle is included.
