A Design Strategy for Large Dielectric Radome Compensated Joints

The joint of a large dielectric radome is described in terms of an equivalent transmission-line circuit thanks to the introduction of an equivalent periodic structure and by Floquet´s modal analysis. In this framework, all the dielectric layers are modeled with their corresponding generalized scattering matrices, and the compensation grid is described as a parallel lumped admittance. Its value is the design parameter used to obtain the joint compensation. The measurements on a C-band prototype show a significant compensation effect for both polarizations.
