Abstract:
Network hardware devices organized in a Wireless mesh network (WMN) in which the network hardware devices cooperate in distribution of content files to client consumption devices in an environment of limited connectivity to broadband Internet infrastructure are described. One mesh network device includes a housing including reflective chambers within with multiple antennas are disposed. A first radio is operable to cause a first antenna to radiate electromagnetic energy in a first frequency range and a first reflector chamber is operable to reflect the electromagnetic energy in a first direction away from the housing. Second, third, and fourth radios are operable to cause the respective antennas within the respective reflective chambers to radiate electromagnetic energy and the respective reflective chamber is to reflect the electromagnetic energy in a respective direction away from the housing.

Abstract:
A monolithic dual band antenna is provided. The monolithic dual band antenna includes a first layer comprising a high frequency band antenna. The monolithic dual band antenna further includes a second layer underlying the first layer. The second layer includes a low frequency band antenna. The geometry of the high frequency antenna relative to the low frequency antenna causes resulting electric fields of the high frequency band antenna to be orthogonal to the resulting electric fields of the low frequency band antenna.
Abstract:
An electronic device for communicating in a network is provided. The electronic device includes a circuit board, a frame, a feeding structure formed on the circuit board, and an antenna unit disposed in a plane at a predetermined angle with respect to a surface of the circuit board. In addition, the antenna unit is disposed apart from the frame in electrical connection with the feeding structure.
Abstract:
In an embodiment a method of manufacturing an antenna is disclosed. The method comprises selecting an operating frequency range; identifying a first radiation mode and a second radiation mode of a radiator; determining a configuration of the radiator in which a first frequency within the operating frequency range excites the first radiation mode and a second frequency within the operating frequency range excites the second radiation mode; and making an antenna having a radiator according to the determined configuration.

Abstract:
A rugged patch antenna is described that is low profile and capable of resisting environmental and physical impact. The electrical properties of the antenna do not depend on the nature of the underlying surface. The standing wave ratio, return loss and impedance of the antenna are of sufficient quality to support efficient one and two way communications. The antenna can be mounted on vehicles, aircraft, spacecraft, manhole covers, utility covers, equipment cabinets, personnel and animals.
Abstract:
An antenna is disclosed consisting of a planar ground conductor (16), matching network (20), and resonator (18). The antenna is compact, may operate on one or more frequency bands, and is suitable for high volume production. The antenna exhibits simultaneous dual linear polarizations and a unidirectional pattern in at least one of its operation frequency ranges when configured for multiple-ban operation. Applications for the antenna include wireless communication devices such as cellular telephones or data devices.
