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.

Dual band multiple-input multiple-output antennas

Exemplary embodiments are disclosed of multiport multiband vehicular antenna assemblies. In exemplary embodiments, a multiport multiband antenna assembly may include multiple ports (e.g., three, four, or five ports, etc.) with different combinations of antennas or radiators operable over various frequencies, such as one or more cellular frequencies (e.g., Long Term Evolution (LTE), etc.), internet frequencies (e.g., Wi-Fi, Wi-Fi ISM, etc.), satellite navigation frequencies (e.g., Global Positioning System (GPS), Global Navigation Satellite System (GLONASS), etc.), and/or other frequencies. For example, a multiport multiband antenna assembly may include radiators or antennas operable with LTE, WI-FI, GPS (and/or with other cellular, internet, and/or satellite navigation frequencies) where the radiators or antennas are located and/or part of a single antenna system, e.g., positioned on and/or supported by the same or common base assembly and within the same interior enclosure cooperatively defined by the base assembly and radome of a single roof-mount antenna system, etc.

Multiport multiband vehicular antenna assemblies including multiple radiators

Disclosed herein are various exemplary embodiments of multi-band, wide-band antennas. In exemplary embodiments, the antenna generally includes an upper portion and a lower portion. The upper portion includes two or more upper radiating elements and one or more slots disposed between the two or more upper radiating elements. The lower portion includes three or more lower radiating elements and one or more slots disposed between the three or more lower radiating elements. A gap is between the upper and lower portions such that the upper radiating elements are separated and spaced apart from the lower radiating elements. The antenna may be configured such that coupling of the gap and the upper and lower radiating elements enable multi-band, wide-band operation of the antenna within at least a first frequency range and a second frequency range, with the upper radiating elements operable as a radiating portion of the antenna, the lower radiating elements operable as a ground portion, and the gap operable for impedance matching.

Multi-band, wide-band antennas

Disclosed are exemplary embodiments of multiband antenna assemblies, which generally include helical and linear radiating elements. In an exemplary embodiment, a multiband antenna assembly may generally include at least one helical radiator having a longitudinal axis. At least one linear radiator is aligned with and/or disposed at least partially along the longitudinal axis of the at least one helical radiator. The antenna assembly is resonant in at least three frequency bands.
