Abstract: An antenna device includes a feed coil connected to a feed circuit, and a coil antenna disposed near the feed coil. A ferrite sheet, in which a magnetic loss term in a usable frequency band is relatively large, is provided between the feed coil and the coil antenna. The feed coil and the coil antenna are magnetically coupled to each other via the ferrite sheet. With this configuration, signal transmission efficiency between the feed coil and the coil antenna is enhanced.

Abstract: A circuit board includes a first circuit board portion and a second circuit board portion. The first circuit board portion is provided with a first transmission line for a low-frequency signal or a low-speed signal, and the second circuit board portion is provided with a second transmission line for a high-frequency signal or a high-speed signal. The second circuit board portion is located on the first circuit board portion in a positional relationship in which the first transmission line and the second transmission line are side-by-side with each other. With this structure, signal leakage and interference between different signals are reduced or prevented in a line that transmits signals with different frequencies and different transmission speeds.
