Abstract: An electronic device includes a housing at least partially comprising a metal-material portion, a slit formed in the housing to traverse the metal-material portion along a first direction, and a radiating member, at least a portion is positioned on the slit. The radiating member includes a substrate, a first loop coil pattern formed on a first surface of the substrate, a second loop coil pattern formed on a second surface of the substrate that is opposite the first surface, a connection pattern formed on the first surface of the substrate and connected to each of the first loop coil pattern and the second loop coil pattern, and a bridge pattern formed on the second surface of the substrate and extending in a second direction intersecting the first direction. The bridge pattern bypasses the connection pattern, and is combined with the first loop coil pattern to form a loop coil antenna.

Abstract: An electronic device includes a sheet shaped antenna which is particularly useful for near field communication. The antenna includes a loop type antenna radiator formed on a carrier, the radiator having spiraling loops along an outer region of the carrier. A first feed terminal is provided at one end of the antenna radiator and disposed inside the loops. A second feed terminal is provided at an opposite end of the antenna radiator and disposed outside the loops. The carrier has a cut-out in proximity to the first feed terminal, which enables the first feed terminal to be bent in the same direction as the second feed terminal without bending an outer segment of the antenna radiator adjacent to the cut-out. In this manner, the feed terminals may be defined on a single layer, allowing for a simplified assembly process.

Abstract: A method and a mobile terminal of improving radiation performance and Specific Absorption Rate (SAR) of an antenna are provided. The mobile terminal includes a controller for generating a control signal for switching a ground according to a frequency band used by an antenna, and a switch unit for switching a contact point for each frequency band according to the control signal.
