Abstract

This paper describes design method of spherical reflector antennas with the subreflector between the main spherical reflector and the primary horn in order to correct for spherical aberration. Design parameters are three, namely,an aperture angle of the main reflector, a diameter of the subreflector and a position of the horn. If coordinates of the subreflector are de.ned doubly for some combination of the three parameters, the subreflector cannot be formed. Analytical condition to form the subreflector is deduced using the three desin parameters. In numerical results, a subreflector diameter have much in.uence rather than a horn position for forming condition, the minimum diameter of the forming subreflector exist accordin as an aperture angle of the main reflector. An amplitude distribution in the main reflector is presented for the three design parameters and the illuminated radiation patterns at the subreflector. If the diameter of the subreflector is selected for the minimum value describe above in order to minimize aperture blocking of the subreflector, an extreemly inverse-taped amplitude distribution which have deteriorate radiatin characteristics is produced.
