Abstract:
An ultra-wideband (UWB) antenna for wireless communication in proximity to a human body and between devices having no line-of-sight, includes symmetrical radiators disposed on a side of a dielectric layer, and a differential microstrip feeding line disposed on the side and an opposite side of the dielectric layer. The UWB antenna further includes a top dielectric layer disposed over the side of the dielectric layer, a bottom dielectric layer disposed over the opposite side of the dielectric layer, and a top connecting plate disposed on an outer surface of the top dielectric layer. The UWB antenna further includes a bottom connecting plate disposed on an outer surface of the bottom dielectric layer, and an inter-layer connector configured to connect ends of each of the symmetrical radiators to the top connecting plate and the bottom connecting plate, respectively.
Abstract:
A mobile communication device having a wireless power receiver and wireless communications unit, in which inductors of the communications unit and the power receiver are in close proximity to each other, is provided. The mobile communication device includes a wireless communications unit including a first inductor configured to transmit and receive data via inductive coupling, and a wireless power receiver. The wireless power receiver includes a second inductor which is disposed above the first inductor and receives power via inductive coupling, a ferrite shield disposed between the first inductor and the second inductor, and a compensator disposed between the first inductor and the ferrite shield. Compensator is adapted to compensate for variations in the inductance of the first inductor caused by the ferrite shield.
Abstract:
A small-sized ultra-wideband (UWB) antenna includes a radiating unit configured to have a contour of a first shape, a ground unit configured to have a contour of a shape substantially equal to the first shape, and disposed parallel to the radiating unit, at least one shorting pin connected orthogonal to the ground unit and the radiating unit to connect a first area of the ground unit and a first area of the radiating unit, and a feeding unit connected orthogonal to the ground unit and the radiating unit to connect a second area of the ground unit and a second area of the radiating unit.
