摘要: A dual band array antenna is disclosed having interleaved waveguide and dipole arrays, each operating in a different frequency band. The orientation of the waveguides dipoles such that polarization signals two bands perpendicular to other, thus reducing mutual coupling. are used for higher their cutoff selected be above lower at which operate, order reduce coupling into waveguides. In one embodiment printed on substrate dielectric constant so spacing same as spacing. This eliminates grating lobe formation radiation pattern array. low pass filter included feed circuit reject frequencies operate. As result invention, beams independently simultaneously steerable single aperture.
