摘要： An electronic device may be provided with wireless circuitry and a housing with upper and lower ends. The upper end may include first and second inverted-F antennas formed from portions of conductive peripheral housing structures separated from an antenna ground by a slot. The upper end may include an open slot antenna formed from a portion of the slot. The upper end may include an additional inverted-F antenna that overlap the slot. A parasitic element may be disposed between the open slot antenna and the additional inverted-F antenna and coupled to the antenna ground at a proximal end. A tuning component may be coupled between the parasitic element and the antenna ground.

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： An antenna for a ground-penetration radar system is disclosed. The antenna has a housing that defines a cavity. A radiator is located on a surface of a planar substrate within the cavity. A wear-block is located between the radiator and the opening to the cavity for providing mechanical protection to the radiator. An absorber assembly is located on an opposite side of the radiator from the opening. The absorber assembly comprises a microwave absorber and a first dielectric layer. The first dielectric layer is located between the radiator and the microwave absorber.

摘要： Proposed is a position measuring device configured to measure a position (distance) by combining a TWR positioning method and a PDOA positioning method. The proposed position measuring device: outputs positioning signals at set time intervals; receives response signals for the positioning signals; measures the distance between a plurality of diversity antennas and an object on the basis of the respective positioning signals and response signals transmitted and received by the diversity antennas; and measures the distance to the object on the basis of the measurement values of the distances between the plurality of diversity antennas and the object.
