Disclosed herein are various exemplary embodiments of omnidirectional multiband symmetrical dipole antennas.

Omnidirectional multiband symmetrical dipole antennas

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.

Multiband antenna assemblies

Disclosed herein are various exemplary embodiments of omnidirectional multi-band antennas. In an exemplary embodiment, an antenna includes upper and lower portions. The upper portion includes one or more radiating elements, one or more tapering features for impedance matching, and one or more slots configured to enable multi-band operation of the antenna. The lower portion includes one or more radiating elements and one or more slots.

Omnidirectional multi-band antennas

Multi-band dipole antennas for wireless application devices are disclosed. An example antenna includes at least one dipole including a resonant element and a ground element. A feed point is coupled to the resonant element, and a ground point is coupled to the ground element. The example antenna also includes a parasitic element adjacent at least a portion of the resonant element. The parasitic element is coupled to the ground element and configured to be operable for changing a resonant frequency of at least a portion of the resonant element.

Multi-band dipole antennas

Exemplary embodiments are provided of multiband high gain omnidirectional antennas. In one exemplary embodiment, an antenna generally includes first and second radiating elements. The first radiating element is configured to produce a first radiation pattern at a first operating frequency. The second radiating element is configured to produce a second radiation pattern at a second operating frequency. Each of the first and second radiating elements includes a meandering or helical portion.
