Analysis of an anisotropic dielectric radome

A grooved-dielectric flat radome panel is analyzed in terms of an arbitrary direction of incidence on
N
planar slabs each of which is dielectrically anisotropic, homogeneous, and lossless. Using this model for the grooved panel, transmission coefficients of 90 percent or greater over a 10:1 frequency band and over
0\deg
to
60\deg
incidence angle are predicted and demonstrated experimentally. Measurements are presented on two panels from 3 to 35 GHz.
