Abstract: An electronic device is provided. The electronic device includes a housing structure including a first housing and a second housing connected to first housing, the second housing being connected to the first housing so as to be slidable while being at least partially inserted into or withdrawn from the first housing, a sensor module including at least one sensor, an antenna, an antenna tuner electrically connected to the antenna and configured to match impedance of the antenna, and a processor operatively connected to the sensor module, the antenna, and the antenna tuner, wherein the processor is configured to determine withdrawal information about a withdrawn degree of the second housing by using the sensor module, select an index corresponding to the withdrawal information from among multiple indices in which impedance values of the antenna according to multiple different pieces of withdrawal information are sampled, and control, based on a tuning code corresponding to the selected index, the antenna tuner to activate or deactivate at least some among at least one of one or more capacitors or one or more inductors included in the antenna tuner, so as to match the impedance of the antenna.

Abstract: Various embodiments relate to an electronic device and a method for outputting an alert, and a system comprising a locking device coupled to the electronic device. To this end, the electronic device, according to various embodiments, comprises: a connection terminal; and a processor, wherein the processor is configured to: detect a connection with a locking device via the connection terminal; receive an identifier of the locking device from the locking device; identify the received identifier to set the electronic device in an alert mode; detect a disconnection between the electronic device and the locking device; and output an alert in response to the detected disconnection. Other embodiments may be possible.
