Abstract:

The feasibility of designing and constructing a high gain, broadband, inertialess scanned antenna at millimeter frequencies 30-100 Gc for aerospace applications was investigated. Quasi-optical ferromagnetic beam scanning was studied analytically and experimentally. The results demonstrated that a scannable millimeter antenna is feasible. Quasi-optical diffraction grating techniques, where both the spacing between grating elements and the distance depth between grating elements can be used to realize scanning, were studied analytically. A third technique was studied, in which a small aperture ferromagnetic scanner is used with scattering and spherical optics. The conclusions contain detailed descriptions of the antenna systems using either cubic lattice ferrites or hexagonal lattice ferrites. In addition, the technique employing ferromagnetic materials as scattering mechanism spherical optics is detailed. Author
