Abstract: Exemplary embodiments are disclosed of dual-band multiple-input multiple-output (MIMO) antennas. In an exemplary embodiment, an antenna generally includes a circuit board, a first antenna radiating element positioned on the circuit board, a second antenna radiating element positioned on the circuit board, and at least two antenna feeding elements extending from the circuit board. Each of the at least two antenna feeding elements is electrically connected with a different one of the first and second antenna elements.

Abstract: Disclosed are exemplary embodiments of antennas that may be configured to be low profile, omnidirectional, ceiling mountable, and/or multiple-input multiple-output (MIMO). In an exemplary embodiment, an antenna generally includes first and second radiators and a ground plane. First and second edge portions of the ground plane may configured to be operable for reducing null at azimuth plane to thereby allow the antenna to have more omnidirectional radiation patterns for the azimuth plane. The antenna may be configured to have an asymmetrical perpendicular dipole configuration. A neutral line may be spaced apart from and proximity coupled to the ground plane. The ground plane may comprise first and second ground plane extension arms and/or a slant cutout defined between spaced-apart first and second lower portions of the ground plane. The ground plane may include a bridge portion extending between the spaced-apart first and second lower portions of the ground plane.

Abstract: Exemplary embodiments are provided of antenna housing assemblies. In an exemplary embodiment, an assembly generally includes a radome having an outer surface, an inner surface, a first end, and a second end opposite the first end. A top cap is coupled to the first end of the radome via an ultrasonic weld joint. A first sealing member is disposed about the top cap such that the first sealing member is positioned between the top cap and the inner surface of the radome. A bottom cap is fastened to the second end of the radome via an ultrasonic weld joint. A second sealing member is disposed about the bottom cap such that the second sealing member is positioned between the bottom cap and the inner surface of the radome. Exemplary methods of assembling antenna housings are also disclosed.
