    摘要： An electronic device is provided. The electronic device includes a housing. The housing includes a first plate that is directed outward in a first direction, a second plate that is directed outward in a second direction opposite to the first direction, and a side member that surrounds a space between the first and second plates. The electronic device further includes a first antenna structure located in the space, wherein the first antenna structure includes a first conductive structure including a first conductive layer, which is substantially parallel to the second plate and includes a first edge extending in a third direction perpendicular to the first direction and a first notch portion disposed at the first edge, and a first conductive wall, which is substantially perpendicular to the first conductive layer and includes a second notch portion extending from the first edge and connected to the first notch portion. The electronic device further includes a second conductive structure located in the first notch portion and electrically isolated from the first conductive structure; and a third conductive structure located between the first conductive layer and the first plate and electrically isolated from the first conductive structure and the second conductive structure. The third conductive structure includes a second conductive layer facing the first conductive layer and having a quadrilateral shape, the second conductive layer including a second edge extending parallel to the first edge, a third edge extending perpendicular to the second edge, a fourth edge extending parallel to the third edge, and a fifth edge extending parallel to the second edge, wherein a distance to the fifth edge from the first conductive wall is shorter than a distance to the second edge from the first conductive wall, a second conductive wall facing the first conductive wall and extending from the second edge, a third conductive wall connected to the third edge and the second conductive wall and perpendicular to the second conductive layer and the second conductive wall, and a fourth conductive wall connected to the fourth edge and the second conductive wall and perpendicular to the second conductive layer and the second conductive wall. The electronic device further includes a wireless communication circuit electrically connected to the second conductive structure and configured to transmit or receive a signal having a frequency of 3 GHz to 100 GHz.

    摘要： A display driver circuit includes a source driver configured to output display data to data lines, a controller configured to control the source driver, based on a synchronization signal, and a frequency adjusting circuit configured to extend a first time interval of the synchronization signal from a first length to a second length, such that time interval in which the display data is not output to the data lines is extended, when second image data are not received from an external device during a reference time interval after first image data are received from the external device, and shorten the first time interval, from the second length to a third length, when an instruction is received from the external device after the first time interval is extended to the second length.

    摘要： Various embodiments of the present invention relate to an unmanned aerial vehicle (UAV) and method for operating the same, and an automated guided vehicle (AGV) for controlling movements of the unmanned aerial vehicle. The unmanned aerial vehicle according to various embodiments of the present invention may comprise: a wireless communication circuit; at least one sensor; a processor operatively connected to the wireless communication circuit and the at least one sensor; and a memory operatively connected to the processor, wherein the memory stores instructions that, when executed, cause the processor to: receive a movement command for a movement with respect to the current location of the unmanned aerial vehicle, from an automated guided vehicle located within a predetermined distance from the unmanned aerial vehicle, by using the wireless communication circuit; acquire location-independent sensing information by using the at least one sensor, while the unmanned aerial vehicle moves according to the movement command; and transmit the location-independent sensing information to the automated guided vehicle so as to allow the automated guided vehicle to determine the location of the unmanned aerial vehicle by using the location-independent sensing information.
