Abstract

A radar antenna element comprises a lower band waveguide and an array of parallel, dual-polarized, higher band waveguides and dipoles mounted within or directly adjacent an aperture of the lower band waveguide. The lower band waveguide and each higher band waveguide have one cross-sectional dimension less than 0.5 wavelength. A choke section, tuned dielectric or absorber isolates signals of the higher band waveguides from signals of the lower band waveguide. An array of such radar antenna elements locates a radar target with lower band signals and tracks that target with higher band signals, for instance.
