Abstract

A multi-frequency radome includes a material-tuned radome portion for generating a low frequency passband of the radome and an integrated low pass frequency selective surface (FSS) portion for tuning a high frequency passband of the radome. The FSS portion provides a reactance necessary to move an upper passband of the material-tuned radome to a desired spectral location. Because the FSS portion is a low pass structure relative to the low frequency passband of the material-tuned radome portion, it does not substantially affect the low frequency passband when the FSS portion is applied to the material-tuned radome. In one embodiment, the FSS portion is designed to take advantage of various well known properties of FSS structures, such as the ability to tune for angle of arrival and polarization properties.
