Parabolic-Antenna Design for Microwaves

This paper is intended to give fundamental relations and design criteria for parabolic radiators at microwave frequencies (i.e., wavelengths between 1 and 10 centimeters). The frst part of the paper discusses the properties of the parabola which make it useful as a directional antenna, and the relation of phase polarization and amplitude of primary illumination to the over-all radiation characteristics. In the second part, the characteristics of practical feed systems for parabolic antennas are discussed.
