Patent ID: 7142169

Claim:
A microwave antenna position control apparatus cooperative with a microwave communication antenna positionable in azimuth and elevation, said microwave communication antenna comprising a first narrow electromagnetic beam emanating from an origin on said microwave communication antenna, said first electromagnetic beam having a fixed direction relative to said microwave communication antenna, said microwave antenna position control apparatus comprising: a) a multiplicity of dielectric rod radiator elements proximate said microwave communication antenna, said multiplicity of dielectric rod radiator elements symmetrically positioned relative to said fixed direction, b) each of said dielectric rod radiator elements equidistant from said origin of said first electromagnetic beam, the axis of each of said dielectric rod radiator elements canted at an angle away from said fixed direction, c) means for electromagnetically coupling said multiplicity of dielectric rod radiator elements, whereby the resultant radiation pattern of said multiplicity of dielectric rod radiator elements is an electromagnetic radiation pattern in the form of an electromagnetic “well” having symmetry about said fixed direction, d) means for deriving elevation and azimuth control signals from said electromagnetic radiation pattern “well”, whereby on reception of an incoming electromagnetic beam by said microwave antenna position control apparatus, said microwave communication antenna is positionable in elevation and azimuth so that said fixed direction is coincident with said incoming beam to facilitate communication with the source of said incoming beam.
