摘要： A system for harvesting energy for a vehicle includes an antenna, a DC bus, a receiver circuit, and an electrical load. The antenna is located on the vehicle and is configured to receive a plurality of signals in at least one of a 2.4 gigahertz band and a 5.9 gigahertz band. The receiver circuit is coupled to the antenna and the DC bus. The receiver circuit is configured to convert the plurality of signals to a DC signal that is transmitted onto the DC bus. The electrical load is coupled to the DC bus and is configured to operate at least when the vehicle is not running using the DC signal supplied by the receiver circuit.

摘要： Example implementations relate to mixed mode slot antennas. Mixed mode slot antennas may be implemented in a display housing of a communication device. A mixed mode slot antenna unit may include a first PCB attached to a first metal layer to form a first mode antenna, where the first metal layer includes a first slot, and the first metal layer is a metal back cover of the display housing of the communication device. The mixed mode slot antenna unit may also include a second PCB coupled to the first PCB to form a second mode antenna, where the second metal layer includes a second slot, and where the second metal layer is a metal front cover of the display housing; and a non-conductive layer disposed between the first PCB and the second PCB to provide insulation between the first PCB and the second PCB.

摘要： Wireless mesh network (WMN) architectures of network hardware devices organized in a mesh topology 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 is described. A self-contained, fully connected WMN can be used for localized delivery of content files. One WMN includes a single ingress node for ingress of content files into the wireless mesh network. The WMN also includes multiple network hardware devices wirelessly connected through a network backbone formed by multiple P2P wireless connections. A first network hardware device is wirelessly connected to a client consumption device by a first node-to-client (N2C) wireless connection and a second network hardware device is wirelessly connected to the single ingress node.

摘要： Slotted planar inverted F antennas are provided that can be operated in multiple frequency bands and are usable with electrically small ground planes. The antennas may have multiple planar levels and the impedance of each level (corresponding to a particular frequency band) may be independently adjustable. The antennas may have a self-supporting structure that does not require a separate frame. The antennas may further have a right hand circular polarization hemisphere and a left hand circular polarization hemisphere. Multiple antennas may be situated orthogonally to one another without adversely affecting their performance, due to the hemispherical polarizations, and thereby provide polarization diversity. The number of antennas and associated components used in wireless communications devices may be reduced by using the antennas, as well as reducing the amount of space needed for the antennas.

摘要： A dual broadband and multiband antenna system of reduced dimension may be used as external antenna for vehicles. The antenna system includes first and second radiating elements and a flat ground plane in common with the two radiating elements. The two radiating elements are placed above an upper surface of the ground plane, and each radiating element is folded and has a vertical and horizontal surface. The vertical surfaces of the two radiating elements are substantially orthogonal to the ground plane and substantially parallel to each other. The horizontal surfaces of the two radiating elements are substantially coplanar and substantially parallel to the ground plane. The antenna system is preferably adapted to operate on the LTE communication network and provides 5G communication services.

摘要： Antenna elements (101, 102) used for multi-band antenna dual polarization include: four radiating elements (201), a balun element configured to feed power to the radiating elements (201), and a fastening plate (202) configured to fasten the balun element. The balun element includes two dielectric plates (203). Two signal transmission units (301), one feeding unit (401), and two filtering units (402) are printed on each dielectric plate (203). An LC resonant energy storage structure is constructed on the balun element by using the filtering units (402), and decoupling on a specific frequency band can be implemented by adjusting the filtering unit (402). Therefore, even if the antenna elements (101, 102) are applied to a scenario in which elements on different frequency bands work collaboratively, radiating elements (201) on different frequency bands are not coupled electromagnetically and strongly when the radiating elements are arranged closely.
