Abstract

The present study shows that the graded dielectric inhomogeneous radome exhibits better EM performance characteristics than monolithic half-wave and sandwich radome wall configurations (with either CTR or VTR designs) and provides a bandwidth of 500 MHz from 9.75 to 10.25 GHz with center frequency at 10 GHz. The proposed design gives superior performance for the entire forward hemisphere in terms of co-pol (>−0.5 dB), cross-pol (<−30 dB), boresight error (<3 mrad) and also shows minimal pattern degradation. The excellent EM performance characteristics together with fabrication easiness make graded dielectric radome an exceptional design for both airborne and ground-based radome applications.
