摘要： Various embodiments of an antenna device for a wireless terminal are disclosed. The antenna device includes a radiator configured to be extracted from/retracted into the wireless terminal, a L-C lumped circuit, and a noise removing coil coupled between the radiator and the L-C lumped circuit, to attenuate noise introduced through the radiator. The radiator may be configured as a helical coil or at least one meandering printed pattern so as to reduce its overall length while maintaining a desired electrical length. In embodiments, the antenna device is useful for UHF/VHF frequency bands. Multi-band configurations are disclosed. In one embodiment, a stainless steel tube member substantially surrounds a helical coil, and the tube member operates at a lower frequency band than the helical coil.

摘要： Apparatus and methods in a near field communication capable electronic device are disclosed. An antenna receives a near field signal from a recharging pad or a reader to provide a reception signal. A detector coupled to the antenna receives the reception signal and detects therefrom a voltage, current or power value representing a power level of the near field signal. A switch is coupled to the detector, and switches the reception signal corresponding to the recharging pad or the reader to a recharging transceiver to recharge a battery, or to a near field communication transceiver, respectively, on the basis of the detected voltage. A Hall-effect type magnetic sensor may be used as an alternative to the detector.

摘要： An electronic device includes a display, a memory configured to store instructions, a fingerprint sensor configured to obtain first fingerprint information regarding a finger contacting the display, and a processor, and when executing the instructions, the processor is configured to while displaying a first screen on the display, receive a first drag input from a user's finger contacting the display; obtain the first fingerprint information regarding the finger by using the fingerprint sensor while the first drag input is maintained; and, based on it being identified that the fingerprint information matches first reference fingerprint information, display a second screen converted from the first screen at least partially on the display.
