Abstract: A coil device includes a board, a first pattern formed on one surface of the board, and a second pattern formed on the other surface of the board. At least one pattern via electrically connects the first pattern and the second pattern to each other. A via region, corresponding to a region in which the pattern via is formed in the first pattern, includes n first conducting wires (where n is a natural number of 1 or more). At least a portion of the first pattern, excluding the via region in the first pattern, includes m first conducting wires (where m is greater than n and is a natural number of 2 or more).

Abstract: A wireless communication antenna comprises a magnetic body and coil portions. The coil portions have a solenoid shape formed around the magnetic body defining a core. The coil portions are spaced apart from each other and connected to each other in series. Magnetic fields radiated by the coil portions overlap each other and each of the coil portions comprises: a first wiring portion disposed on a first surface of the magnetic body; a second wiring portion disposed on a second surface of the magnetic body; and conductive vias interconnecting the first wiring portion and the second wiring portion.

Abstract: There are provided a coil device and an apparatus including the same. The coil device includes a first coil and a second coil. The first coil is configured to receive a first signal using a first magnetic field formed in a first direction. The second coil includes a shape different from the first coil and is configured to form a second magnetic field in a second direction, different from the first direction, to transmit a second signal, different from the first signal.

Abstract: There are provided an information transmitter and an apparatus including the same. The information transmitter includes a signal generator configured to output an information signal including pulses changed from a first state to a second state or a third state and subsequently changed from the second state or the third state to the first state. A time period in which some of the pulses are changed from the first state to the second state or the third state may be shorter than a time period in which some of the pulses are changed from the second state or the third state to the first state. The information transmitter also includes a transmitting coil configured to receive the information signal and generate a magnetic field based on the information signal.
