摘要： An electronic device is provided. The electronic device includes a housing, an antenna structure, a first conductive material, and a second conductive material. The housing may be configured to provide a front surface and a rear surface of the electronic device. The antenna structure includes a printed circuit board positioned in the housing. The printed circuit board includes a first surface configured to face the front surface or the rear surface and a second surface configured to face a direction opposite to the first surface. The printed circuit board includes a first conductive layer, a second conductive layer, and a dielectric. The first conductive layer includes a first antenna element and a second antenna element which are configured so as not to overlap each other when viewed from above the first surface.

摘要： An electronic device includes a housing including a front plate, a rear plate facing away from the front plate, and a side member surrounding a space between the front plate and the rear plate and connecting one side of the front plate to one side of the rear plate, an antenna structure including at least part of the conductive portion, and a printed circuit board disposed in the space and including at least one processor. At least part of the side member is a conductive portion. The conductive portion includes a first conductive pattern, a second conductive pattern disposed at least partially coupled to the first conductive pattern, and a third conductive pattern disposed at least partially coupled to the first conductive pattern and spaced apart from the second conductive pattern. The antenna structure includes a first feeding part electrically connected to a first location of the first conductive pattern, a second feeding part electrically connected to a second location of the first conductive pattern, wherein the second location is closer to the third conductive pattern than the first location, a first ground part electrically connected to a third location between the first location and the second location of the first conductive pattern, a second ground part electrically connected to a fourth location between the second location and the third location of the first conductive pattern, a switch electrically connected to a fifth location between the first location and the third location of the first conductive pattern, a third ground part electrically connected to a sixth location of the second conductive pattern, and a fourth ground part electrically connected to a seventh location of the third conductive pattern.

摘要： A fingerprint recognition-based control method may include acquiring sensor data with a fingerprint sensor. The sensor data may be acquired by the fingerprint sensor in response to a contact between a physical object and a sensing area of the fingerprint sensor. The method may further include receiving an input through a first input receiver from among one or more input receivers. The first input receiver may be located in a vicinity of the fingerprint sensor. The method may further include verifying the sensor data to be an input fingerprint; and sensing a motion of the physical object based on the acquired sensor data and the received input, in response to a positive result of the verifying.

摘要： A processor-implemented object tracking method includes: setting a suppressed region in a template image based on a shape of a target box of the template image; refining a template feature map of the template image by suppressing an influence of feature data corresponding to the suppressed region in the template feature map; and tracking an object by determining a bounding box corresponding to the target box in a search image based on the refined template feature map.
