Abstract: 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.

Abstract: An array antenna module includes multiple antenna assemblies. Each antenna assembly generally includes a first radiating element and a second radiating element spaced apart from the first radiating element and capacitively coupled thereto. A first transmission line is capacitively coupled to the first radiating element, and a second transmission line is electrically coupled to the first radiating element by a connector. The antenna assembly is operable to transmit at least one or more signals to at least one or more wireless application devices and/or to receive at least one or more signals from at least one or more wireless application devices. The first radiating element, second radiating element, first transmission line, and/or second transmission line are coupled to substrates. And at least one or more of the substrates may include epoxy resin bonded glass fabric such as, for example, flame retardant 4.
