Panel or Patch Wall-Mount Directional Antennas

Panel or patch antennas are designed to mount to a wall and provide coverage to an area such as an auditorium or large meeting room. They are fairly small in size and can even be painted to blend in with the wall (as long as the paint is nonmetallic). Figure B-9 shows a 6-dBi diversity patch antenna from Cisco Systems.
