Abstract
A radio frequency (RF) antenna unit that includes a first antenna and a second antenna. The first antenna is positioned on a reflector element, and includes at least three inverted-F antenna (IFAs) elements that are electrically connected to a first RF signal port and that each have an associated tunable element that controls excitation of the IFA element, the tunable elements being operative to control a polarization direction of the first antenna. The second antenna is co-located on the reflector element with the first antenna, and includes a plurality of antenna elements.
