Patent attributes
A radio frequency (RF) antenna array that includes a first antenna unit that operates at a first frequency band and includes three antenna elements that are collocated on a reflector element, each of the three antenna elements having a different polarization direction than the other two antenna elements of the first antenna unit. A first switch is associated with the first antenna unit and a first conductive line for selectively connecting each one of the antenna elements of the first antenna unit to the first conductive line. A second antenna unit that operates at a second frequency band also includes three antenna elements that are collocated on the reflector element, each of the three antenna elements having a different polarization direction than the other two antenna elements of the second antenna unit. A second switch is associated with the second antenna unit and a second conductive line for selectively connecting each one of the antenna elements of the second antenna unit to the second conductive line.
