Antenna housing

Disclosed are exemplary embodiments of omnidirectional broadband antennas. In an exemplary embodiment, an antenna generally includes a ground element, an antenna element, and an annular patch element. The antenna element may be electrically isolated from the ground element. The antenna element may include at least one portion that is substantially conical, substantially pyramidal, and/or that tapers in a longitudinal direction. The annular patch element is electrically grounded to the ground element. The annular patch element surrounds at least a portion of the antenna element and is parasitically coupled to the antenna element.

Omnidirectional broadband antennas

Exemplary embodiments are provided of omnidirectional MIMO antennas with polarization diversity. In one exemplary embodiment, an omnidirectional MIMO antenna generally includes an array of radiating antenna elements having a linear horizontal polarization and radiating omnidirectionally in azimuth. The antenna also includes at least one radiating antenna element having a linear vertical polarization and radiating omnidirectionally in azimuth. The vertically polarized radiating antenna is spaced-apart from the array. The antenna is operable for producing omnidirectional, vertically polarized coverage for at least one port, as well as omnidirectional, horizontally polarized coverage for at least one other port.

Omnidirectional multiple input multiple output (MIMO) antennas with polarization diversity

A bracket for securing an antenna to a ceiling grid system has a first opening to allow the bracket to be secured to a connector mechanically coupled to the ceiling grid system and a second opening to allow an electrical connection to pass therethrough. The second opening is offset a distance from the first opening to allow the electrical connection to extend upwardly without being obstructed by the ceiling grid.

System and method for securing an antenna

An antenna includes a differential transmission line and a center conductor, where the center conductor is at least partially contained within the differential transmission line and at least partially protruding therefrom. A first conductive flat element is connected to the center conductor and a flat meander-line structure is integral with the first conductive flat element. In addition, a second conductive flat element is integral with the flat meander-line structure.
