  • Patent number: 10263345
    Abstract: 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.

  • Publication number: 20170194701
    Abstract: Exemplary embodiments are provided of antennas and antenna systems including the same. In an exemplary embodiment, an antenna generally includes a substrate, a radiating element along the substrate, and a ground element along the substrate. The radiating element includes a high band radiating arm and a low band radiating arm. The antenna may further include one or more resistors for separately controlling peak gain for the high and low bands. Additionally, or alternatively, the antenna may include a ground plane arm along the substrate and a waveguide coplanar transmission line along the substrate for feeding the radiating element. The antenna may comprise a printed circuit board (PCB) dipole antenna. In another exemplary embodiment, an antenna system generally includes first and second PCB dipole antennas. Each PCB dipole antenna may include a high band radiating element or arm and a low band radiating element or arm.

  • Patent number: 9595755
    Abstract: According to various aspects, exemplary embodiments are disclosed of ground independent multi-band antenna assemblies. In an exemplary embodiment, a ground independent multi-band antenna assembly is operable within at least a first frequency range and a second frequency range different than the first frequency range. The antenna assembly generally includes an annular ground element, a feed element, a patch element, and a high band element. The feed element includes a feeding point and a shorting point electrically connected to the annular ground element. The patch element is electrically shorted to the annular ground element by the feed element. The high band element is electrically connected to the feed element.
