摘要： An antenna array assembly comprises a ground plate, an array of radiator elements disposed in a spaced relationship with a first face of the ground plate between first and second substantially parallel conductive walls projecting from the first face of the ground plate, and a first and second conductive plate. Each of the first and second conductive plates is electrically isolated from the ground plate, and each is disposed in an upstanding relationship to the first face of the ground plate in a substantially parallel relationship with the first and second conductive walls. This provides reduced radiation in at least one direction in the hemisphere on the opposite side of the ground plate to the first face.

摘要： Systems and devices relating to dipole antennas. The beamwidth of a crossed dipole antenna is widened by providing a parasitic monopole antenna adjacent to the crossed dipole antenna. In one configuration, each arm of the crossed dipole antenna has, adjacent to it, a parasitic monopole antenna. In another configuration, the crossed dipole antenna is surrounded by a number of other crossed dipole antennas acting as parasitic monopole antenna elements. The center or primary crossed dipole antenna can be for low band signals while the secondary crossed dipole antennas are for high band signals.

摘要： 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.

摘要： On-board heat dissipation can be achieved in radio frequency (RF) modules by integrating a heat sink into the RF module's antenna reflector. Said integration achieves a compact and aesthetically pleasing RF module design that reduces the overall footprint of modular active antenna systems (AASs). Embodiment antenna reflectors include portions that are perforated and/or exposed to free flowing air to provide enhanced heat dissipation capability.
