ABSTRACT:
According to one embodiment of the invention, an array antenna includes a substrate body, a first antenna element, and a second antenna element. The first antenna element is coupled to the substrate body and is operable to transmit or receive a first signal. The second antenna element is coupled to the substrate body and is operable to transmit or receive a second signal. The first antenna element is of a different type than the second antenna element. The direction of polarization of the first signal is different than the direction of polarization of the second signal.
