A circuit board is provided in which a transmission loss is reduced. The circuit board includes a first layer; a transmission line disposed on the first layer; and a second layer stacked with the first layer. The second layer includes a first region, which is constructed of a first material, corresponding to a position of the transmission line, and a second region, which is constructed of a second material having a permittivity that is different from that of the first material, corresponding to the position of the transmission line.

Circuit board for reducing transmitting loss and electronic device therewith

An antenna ground structure of a mobile terminal is disclosed. The antenna ground structure of a mobile terminal is arranged to provide the ground pattern on a Printed Circuit Board (PCB) adjacent to the antenna and to electrically connect the ground pattern to the ground unit of the antenna, so that the area of the ground of the antenna may be expanded to improve Specific Absorption Rate (SAR) and communication performance.
