Abstract
Disclosed are exemplary embodiments of multiband WiFi directional antennas. In an exemplary embodiment, an antenna generally includes 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. Each antenna element module includes a radiating element and a ground plane/reflector. The antenna may be operable within at least a first WiFi frequency range and a second WiFi frequency range different than the first WiFi frequency range.

An antenna operable within at least a first WiFi frequency range and a second WiFi frequency range different than 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 said antenna element module includes a radiating element and a ground plane/reflector, whereby the radiating element is operable for radiating a symmetrical directional beam at a direction generally perpendicular and away from the ground plane/reflector at the first and second WiFi frequency ranges.
A multiband WiFi directional antenna comprising a base plate;
- one or more vertically polarized antenna element modules on the base plate;
- and
- one or more horizontally polarized antenna element modules on the base plate;
- wherein each said antenna element module includes:
- a radiating element;
- a feeding element configured to be operable for exciting the radiating element;
- and
- a ground plane/reflector having a bottom portion coupled to the radiating element, and one or more sidewalls that are disposed generally around the radiating element;
- whereby the multiband WiFi directional antenna is operable within at least a first WiFi frequency range and a second WiFi frequency range different than the first WiFi frequency range.
