Some demonstrative embodiments include devices, systems and/or methods of wireless communication via a dual directional antenna. For example, a device may include a hinge to connect between first and second elements to allow rotating the first element between first and second rotational states with respect to the second element, and a rotatable dual directional wireless communication antenna coupled to the hinge. The dual directional wireless communication antenna may be configured to communicate wireless communication signals in a first direction, when the first element is at the first rotational state, and to communicate the wireless communication signals in a second direction, different from the first direction, when the first element is at the second rotational state.
