    Abstract: A 360 degree scanning antenna is disclosed which includes a mechanism for anning the main beam of a cylindrical array in azimuth and over a limited angle in elevation in which a primary feedhorn illuminates a geodesic lens which in turn illuminates the cylindrical array structure. Energy is coupled from the parallel plate structure of the feedhorn assembly into the individual waveguides of the array via dielectric wedges extending from the waveguides.Scanning in elevation is accomplished by changing the transmitter frequency and in azimuth by rotating the primary feedhorn assembly.
