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 C-band prototype show a significant compensation effect for both polarizations
