Abstract: An antenna comprises a coil element, a first metallic plate element, a second metallic plate element and terminals. The first metallic plate element and the second metallic plate element each have the shape of a triangle or an isosceles trapezoid. Further, the first metallic plate element and the second metallic plate element are mirror symmetric with respect to a symmetry plane that is perpendicular to the longitudinal direction. The antenna provides a wider area of use at small size and can thus be used for different transmission technologies, such as NFC and UWB.

Abstract: In an aspect, a user equipment (UE) determines a mutual coupling signal associated with a transmit antenna and a receive antenna, determines a mutual coupling difference between the mutual coupling signal and a reference signal, determines a beat signal difference between a current beat signal and a previous beat signal, and determines an amount of micro-motion that is present within a near field. The UE determines whether human tissue is present within the near field based on the mutual coupling difference and the amount of micro-motion. Based on determining that the human tissue is present within the near field, the UE determines an amount of radio frequency exposure associated with the human tissue. Based on determining that the amount of radio frequency exposure exceeds a maximum permissible exposure, the UE reduces the amount of radio frequency exposure associated with the human tissue.

Abstract: A communication device includes a conductive chassis, an electrical feed positioned within the conductive chassis and configured to supply a communication signal, an edge antenna at least partially formed in the conductive chassis at an edge of the communication device, and a conductive coil positioned within the conductive chassis in proximity to the edge antenna. The conductive coil is configured to receive the communication signal from the electrical feed and to generate a magnetic field corresponding to the communication signal that inductively drives the edge antenna to radiate a radio frequency signal corresponding to the communication signal.
