摘要： An electronic device may be provided with control circuitry and doublets of first and second antennas that are used to determine the position and orientation of the device relative to external wireless equipment. The control circuitry may determine the relative position and orientation of the external equipment by measuring the angle of arrival of radio-frequency signals from the external equipment. Each doublet may include first and second cavity-backed slot antennas. The first and second antennas may each include a first slot element that is directly fed and a second slot element that is parasitically fed by the first slot element. The first slot element may radiate in an ultra-wideband communications band at 8.0 GHz and the second slot element may radiate in an ultra-wideband communications band at 6.5 GHz. The doublet may be aligned with a dielectric window in a conductive sidewall for the device.

摘要： An ultra wide band (UWB) antenna includes: (i) an array of antenna elements spaced from a central axis; and (ii) a network of lossy feedlines respectively communicatively coupled to the array of antenna elements. Each lossy feedline is periodically loaded with a resistance that is capacitively coupled to ground. Respective lengths of each lossy feedlines are selected to increase with an increase in distance from the central axis to achieve frequency independence of a radiated beamwidth from the UWB antenna.

摘要： Embodiments of the present disclosure relate to a UAV comprising a fuselage, a rotor, and a patch antenna element. The patch antenna element, which is provided from a patch antenna stack-up, is conformally disposed on an outer surface of the UAV's fuselage. The patch antenna comprises a first substrate, patch conductor, intermediate substrate, bottom substrate, and ground plane. The patch conductor is disposed on a top surface of the first substrate. A first surface of the intermediate substrate, which is a magneto-dielectric material, is disposed on a bottom surface of the first substrate. A top surface of the bottom substrate is disposed on a second surface of the intermediate substrate. A ground plane conductor is disposed on a bottom surface of the bottom substrate.

摘要： An apparatus of an antenna is provided. The apparatus includes a first conductor plate disposed on an upper side of a single plate and comprising an aperture, a plurality of vias inserted to vertically penetrate through the single plate, a second conductor plate disposed on a lower side of the single plate, and a feed line for applying a signal to radiate to a dielectric resonator embedded as a cavity which is formed by the first conductor plate, the second conductor plate, and the vias. The aperture is in a size which produces multiple-resonance at an operating frequency.

摘要： A scalable, high-bandwidth connectivity architecture for portable storage devices and memory modules may utilize EHF communication link chip packages mounted in various two-dimensional and three-dimensional configurations on planar surfaces such as printed circuit boards. Multiple electromagnetic communication links between devices distributed on major faces of card-like devices may be provided with respectively aligned pairs of communication units on each device. Adjacent communication units on a printed circuit board may transmit or receive electromagnetic radiation having different polarization, such as linear or elliptical polarization. Power and communication between communication devices may both be provided wirelessly.

摘要： An electronic device including an antenna module is provided. The electronic device includes a 5th generation (5G) antenna module that includes an antenna array, at least one conductive region operating as a ground with respect to the antenna array, and a first communication circuit feeding a power to the antenna array to communicate through a millimeter wave signal, and a printed circuit board (PCB) that includes a second communication circuit and a ground region. The second communication circuit feeds the power to an electrical path at least including the at least one conductive region and transmits or receives a signal in a frequency band different from a frequency band of the millimeter wave signal based on the electrical path supplied with the power and the ground region.

摘要： Methods, systems, and devices are described for low latency communications within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system and may send triggers to initiate communications using a dedicated resource in a wireless communications network that supports transmissions having a first subframe type and a second subframe type, the first subframe type comprising symbols of a first duration and the second subframe type comprising symbols of a second duration that is shorter than the first duration. Communications may be initiated by transmitting a trigger from the UE or eNB using the dedicated resource, and initiating communications following the trigger. The duration of time between the trigger and initiating communications can be significantly shorter than the time to initiate communications using legacy LTE communications.

摘要： A novel geometry, the geometry of Space-Filling Curves (SFC) is defined in the present invention and it is used to shape a part of an antenna. By means of this novel technique, the size of the antenna can be reduced with respect to prior art, or alternatively, given a fixed size the antenna can operate at a lower frequency with respect to a conventional antenna of the same size.
