Abstract : A bootlace microwave lens antenna has orthogonal delay lines for reducing quadratic phase errors to improve focusing capability. The collector and radiator elements consists of mutually orthogonal pairs of subelements with one of the subelements oriented radially and the other oriented tangentially on the respective collector and radiator surfaces. Individual delay lines interconnect corresponding radial and tangential subelements on each surface thus allowing for phase corrections in the axial planes parallel to and perpendicular to the plane of scan by the introduction of an appropriate phase delay in each delay line.
