Abstract :
Describes the method used to design a series of single 90° offset parabolic reflector antennas with a conical corrugated feed horn at 14, 9 and 3 mm wavelengths. The radiation patterns and the phase center are calculated by Gaussian beam mode analysis. The antenna pattern and beam efficiency are calculated by the aperture field method. The experimental data are shown. These antennas were used in microwave and millimeter wave radiometers; demonstrating their mechanical and electrical performance
