摘要： This document describes low-footprint dual-band ultra-wideband (UWB) antenna modules. A described UWB antenna module may be used as an internal part of a mobile device (e.g., cellphone, tablet, and/or other mobile devices). The UWB antenna module includes a multi-layer dual-band antenna that includes a set of multi-layer patch antennas, each patch antenna including a layer with a conductive ground plate, a feeding plate layer, and a parasitic strip layer with two parasitic strips, one configured to resonate at a frequency within a first band of the dual-band antenna, the other configured to resonate at a frequency within a second band of the dual-band antenna. The parasitic strips are electromagnetically coupled to the feeding plate.

摘要： An ultra-wideband dual-polarized tightly coupled bowtie antenna array for ground-based polar ice sounding radar is described. The antenna array has a very large effective aperture to increase the directivity. At the same time, it is lightweight and low profile to minimize the payload and maximize the survey range. In an implementation, the antenna array operates between 180-620 MHz with a fractional bandwidth of 3.4:1. The broadband performance benefits from the tightly coupled antenna elements. A feature of the antenna array is the planar feeding structure without balun. The antenna array element has the microstrip feeding line integrated with one arm of the bowtie antenna. The other arm is directly fed by the microstrip line. By adding a ferrite core around the coax cable for common mode suppression, the bowtie antenna element can be fed differentially without using bulky vertical feeding structure and balun.

摘要： In some aspects, a mobile device may receive, from a transmitting device, the signal by a plurality of antennas. The mobile device may measure one or more phase differences among the signal received at the plurality of antennas. The mobile device may determine a first set of possible values for the angle of arrival that are consistent with the one or more phase differences. The mobile device may measure one or more signal values using one or more sensors of the mobile device. The mobile device may for each of the first set of possible values, determining a confidence score based on the one or more signal values. The mobile device may select, based on the confidence scores, one of the first set of possible values as the angle of arrival.

摘要： In the antenna device, a first insulating plate, a capacitive coupling portion of a tuning plate, a radio wave absorber, a grounding portion of the tuning plate folded back to the back side of the radio wave absorber, and a tuning coated plate provided with a metallic plated film formed on the surface thereof are sequentially stacked below an antenna element having a shape obtained by removing an arched portion from a copper circular plate. Power is supplied from a center conductor of a semi-rigid signal input member to a power feeding unit of the antenna element. An external conductor is held between the upper and lower conductive cushions. A grounding plate is conductive with the external conductor, to ground the grounding portion and the tuning coated plate.

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 may be provided with wireless circuitry and a housing with upper and lower ends. The lower end may include first and second open slot antennas that are directly fed by respective feeds and that radiate in a cellular ultra-high band. The lower end may also include first and second inverted-F antennas. The upper end may include third and fourth inverted-F antennas. The first inverted-F antenna may have a first feed that conveys currents below 2700 MHz and a second feed that conveys antenna currents in the cellular ultra-high band, a wireless local area network band, and/or ultra-wideband frequency bands. If desired, the upper end may include a third open slot antenna that is directly fed by a corresponding antenna feed and that radiates in the cellular ultra-high band and/or in the ultra-wideband frequency bands.
