WiFi multiband directional antennas

摘要

An antenna operable within at least a first WiFi frequency range and a second WiFi frequency range different from the first WiFi frequency range, the antenna comprising: a base plate; a plurality of vertically polarized antenna element modules on the base plate; and a plurality of horizontally polarized antenna element modules on the base plate; wherein each antenna element module comprises a radiating element and a ground plane / reflector, wherein the radiating element is operable to radiate a symmetrical directional beam in a direction generally perpendicular to and away from the ground plane / reflector in the first and second WiFi frequency ranges.
