摘要： A system is described for distributing over the air (OTA) channels within buildings and homes. The system can implement one or more active multi-mode antennas for improved performance and reliability. The system can be configured as a mesh network where multiple nodes are distributed to improve the probability of channel capture across the VHF and UHF frequencies used for over the air TV distribution. A node consists of a beam steering antenna that operates at the VHF and UHF frequencies for TV signal reception, a receiver and demodulation circuit, a transcoder to convert the received information for re-distribution, and a transceiver capable of operation at a secondary frequency band for use in re-distributing the information to communication devices in proximity of the node. The secondary frequency band can be the common WLAN (Wireless Local Area Network) system such as Wi-Fi, with the Wi-Fi transceiver also containing beam steering antennas for improved in-building propagation of the re-distributed information.

摘要： A communication system for an altitude changing object is provided. The communication system can include an antenna system having one or more antennas. The one or more antennas can be associated with a single fixed radiation pattern. The communication system can include one or more processors configured to execute a control routine to perform operations. The operations can include obtaining data indicative of one or more communication parameters associated with the altitude changing object. The operations can include determining a transmit power for each of the one or more antennas based at least in part on the one or more communication parameters. The operations can include controlling the antenna system based at least in part on the transmit power to communicate with a node in the communication network.

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： An antenna comprising an IMD element and one or more parasitic and active tuning elements is disclosed. The IMD element, when used in combination with the active tuning and parasitic elements, allows antenna operation at multiple resonant frequencies. In addition, the direction of antenna radiation pattern may be arbitrarily rotated in accordance with the parasitic and active tuning elements. Unique antenna architectures for beam steering in Wi-Fi band applications is further described.

摘要： The disclosure concerns an antenna with proximity sensor function. The antenna and proximity sensors can be implemented in a laptop computer, and proximity sensor loading states are surveyed and used to determine when and to what degree to alter the reactance at the junction of or along the parasitic element to optimize the frequency response and/or the impedance properties of the antenna system. An algorithm or look-up table is configured to relate proximity sensor loading states to reactance required to alter antenna characteristics.

摘要： A two antenna assembly for use in MIMO systems is described where wide beamwidth performance is achieved over wide frequency ranges while maintaining high isolation and low envelope correlation between the antenna elements in a low profile, small form factor. This MIMO antenna system is optimal for use in DAS systems for in-building applications where a MIMO antenna system is required and a low profile is desirable for ceiling and wall mount applications. The antenna assembly is designed to maintain low Passive Intermodulation (PIM) characteristics across multiple cellular frequency bands. Each antenna in the pair of elements is configured to cover multiple cellular frequency bands to provide a single port per antenna for use with multiple transceivers. A single conductor radiator design for the antenna elements simplifies manufacturing of the antenna. A tuned parasitic element is positioned between the antenna elements to enhance isolation at specific portions of the frequency range.

摘要： An RFIC with memory is described where the memory can be used to house a look-up table for tuning components designed into the RFIC, providing a customized tuning circuit for antenna and transceiver front-end tuning applications. The look-up table can be loaded at wafer level during the manufacturing process to customize an RFIC design for a specific antenna system. The memory can be used to restrict or tailor the tuning range of tunable capacitors and switches within the RFIC to optimize performance in the end application. The resident memory will improve signaling latency when tuning for time critical applications such as channel tuning in a cellular communication system.
