US Patent 8072384 Dual-polarized antenna modules

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.
