Antenna system for millimeter wave length communication systems

摘要

The effect of rain wetting a planar array antenna is reduced substantially by mounting the antenna with its radiating face facing downwards on an angle alpha of about 30-80 DEG to the horizontal and adjusting the angle theta of the main beam of the planar array antenna to its radiating face so that the angle theta of the main beam to the radiating face of the antenna and the angle alpha of the radiating face to the horizontal combine to direct the main beam at the elevation angle omega toward a selected target.
