Abstract
A dual-polarized antenna, and an associated methodology, is provided for a radio device, such as a mobile station. The antenna is formed of a plurality of patches configured into an array, symmetrical in both a first polarization direction and a second polarization direction. Adjacent patches of the array are interconnected by connecting strips that are also symmetrically positioned in the two directions. These connecting strips not only act as feeding lines for the patches but also operate as in-phase radiation elements in each polarization direction. A transverse strip extends between a pair of transversely positioned patches. And a single feed connection is provided thereat.
