Radome impedance matching with metallic circuit elements

It is described how metallic circuit elements may be used in lightweight sandwich radomes to match an otherwise poorly matched structure to free space, to improve performance over a wide range of incidence angles and to enable the design of walls with thicker face ply laminates. Other performance properties that can be obtained with metallic circuit elements are low depolarization, dual or multifrequency capability, and narrow-banding transmissivity. A computer program to optimize thickness and dielectric properties of individual layers of a multilayered radome wall is described.
