摘要： A technique is described wherein one or multiple reflectors are integrated into a wideband antenna to provide directional radiation pattern characteristics across the frequency range serviced by the antenna. Distributed filters are designed into the reflector assembly to alter electrical performance as a function of frequency. The directive properties provided by the reflector assembly can be adjusted at specific frequency bands to provide a more or less directive radiation pattern. The reflector assembly is designed to maintain low Passive Intermodulation (PIM) characteristics making the technique applicable to high quality Distributed Antenna Systems (DAS) and other applications which require low PIM levels and/or a radiation pattern that can be controlled as a function of frequency.

摘要： Antenna systems, devices, and methods for providing both end-fire mm-wave high-frequency signals and low-frequency RF signals from a collocated antenna array in which at least one high-frequency antenna element and a low-frequency antenna element are spaced apart from one another. Grating strips are positioned between the high-frequency antenna elements and the low-frequency antenna element, the grating strips being spaced apart from one another by a defined spacing. The grating strips are configured such that a signal wave from the high-frequency antenna element propagates through the low-frequency antenna element.

摘要： Integrated antenna structures described herein may include planar inverted-F antennas (PIFAs) integrated with artificial magnetic conductor (AMC) metamaterials. The integrated metamaterial operatively coupled with the PIFA may function as an artificial magnetic reflector, sending all the energy radiated upwards, and thereby changing the original omnidirectional radiation pattern of the PIFA to a directional radiation pattern. The integrated antenna structures that include PIFAs and metamaterials may maintain a smaller form factor as compared to similar directional antennas, while exhibiting a suitable performance in terms of radiation efficiency, radiation pattern and impedance bandwidth.

摘要： An antenna assembly includes a first active antenna element and a second active antenna element, each of which may be a dipole. A first set of independently-switchable radio-frequency reflectors are positioned around at least the first active antenna element. These first switchable radio-frequency reflectors may also be positioned around the second active antenna element. Alternatively, a second set of independently-switchable radio-frequency reflectors may be positioned around the second active antenna element. The switchable reflectors enable controlled perturbation of the communication channel between the antenna assembly and a remote communications node, enabling securely encrypted communications.

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 micro controller, RF radios, and antenna switching circuitry. The antenna switching circuitry, in response to the control signals from a micro controller, selectively couples individual ones of a first set of antennas to individual channels of the set of RF radios to communicate content data with client consumption devices and selectively couples individual ones of a second set of antennas to other individual channels of the set of RF radios to communicate content data with other mesh network devices in a WMN.

摘要： A mounting unit (210) securely mounts a radio wave reflection device (200) on a stable installation place such as a pole (20). A reflector unit (300) holds two reflectors (350, 360) at a tilt angle of 45°, allowing the two reflectors (350, 360) to be coaxial and rotatable independently of each other. A joint unit (220) connects the reflector unit (300) and the mounting unit (210). The joint unit (220) has rotational freedom along two axes (AZ axis and EL axis) orthogonal to each other. A radio wave reflecting device that relays, by reflection, radio communications between a first antenna device and a second antenna device distant from each other is thereby provided.
