Abstract
An antenna system with both spatial and polarization diversity having a first antenna aperture and a second antenna aperture, a polarization separation angle formed by the difference between the polarization angle of the first antenna aperture and the polarization angle of the second antenna aperture, and a vertical separation formed by mounting the second antenna aperture a vertical distance above the first antenna aperture, such that diversity gain is achieved by both the polarization angle and the vertical distance. The combination of spatial and polarization diversity allows closer antenna aperture spacing and non-orthogonal polarization angles.
