Exemplary embodiments are disclosed of antennas, antenna systems, and methods of making antennas. In an exemplary embodiment, an antenna generally includes a ground plane and first and second antennas each including a first feed. The antenna system further comprises a neutral line having first and second end portions coupled to the first feed of the respective first and second antennas, and/or one or more decoupling stubs integrally formed from and extending outwardly relative to the ground plane. In another exemplary embodiment, a method of improving isolation between first and second antennas of an antenna system generally includes coupling first and second end portions of a neutral line to a first feed of the respective first and second antennas, and/or integrally forming one or more decoupling stubs from a ground plane.

Omnidirectional antennas, antenna systems, and methods of making omnidirectional 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

An exemplary embodiment of an multiband antenna assembly includes a printed circuit board having a plurality of elements thereon. The plurality of elements may include a radiating element, a matching element, a feed element configured to be operable as a feeding point for the multiband antenna assembly, and a shorting element configured to be operable for electrically shorting the radiating element to ground. The antenna assembly may be operable within at least a first frequency range and a second frequency range different than the first frequency range without requiring any matching lump components coupled to the printed circuit board.
