This paper studies the radiated electromagnetic fields of a circular chirowaveguide mounted on an infinite conducting flange and excited by a dipole antenna. A concept of multilayered structure is introduced and the dyadic Green's functions in different regions are purposely derived by applying the method of scattering superposition and matching the boundary conditions. By means of the dyadic Green's function technique, the radiation characteristics of this structure are discussed in case of an excitation of an infinitesimal electric dipole. The plots of the radiation patterns are provided and some comparisons are also made.

Abstract-This paper studies the performance appraisal of radiation performance of ultra low sidelobe level Active Phased Array Antennas in presence of Multilayer Flat Sandwich Radome. Further, the effect of errors introduced due to amplitude/phase quantisation and planarity of the array surface, on the radiation performance has been studied. Based on these errors, manufacturing tolerances of the Flat Sandwich Radome have been suggested to control the deterioration of radiation performance within tolerable limits. This work is expected to be useful in development/manufacturing of radomes for Active Phased Array Radars and similar applications where ultra low sidelobe levels are required to be maintained.
