Attenuation due to accretion of dust and sand on reflector antennas at microwave frequencies
Abstract
The attenuation due to accretion of dust and sand at the surface of parabolic reflectors is derived theoretically from basic field equations and compared with experimental results. The results are presented for a paraboloid reflector with a radius of 0.6 m and a focal length of 0.4 m at 7 GHz, with the moisture content of the dust and sand assumed to be about 8%. The plots presented demonstrate good agreement between theory and experiment.
