摘要： An electronic device includes a housing providing a front surface and a rear surface, an antenna including a printed circuit board within the housing and including a first surface facing the front surface and a second surface facing the rear surface. The printed circuit board includes a first conductive layer including a first antenna element and a second antenna element that do not overlap each other when viewed from above the first surface, a second conductive layer operating as a ground plane, and a dielectric between the first and second conductive layers. A conductive pattern is located between the front surface and the second surface when the first surface faces the rear surface and is located between the rear surface and the second surface when the first surface faces the front surface. The conductive pattern overlaps a part of the second conductive layer when viewed from above the first surface.

摘要： An electronic device includes a housing antenna formed from a conductive material. At least parts of a side member and a rear cover that constitute the housing of the electronic device are used as an antenna. Accordingly, radiation patterns generated by this antenna are formed on the rear surface of the electronic device as well as at the upper portion of the electronic device. It is therefore possible to perform wireless communication with higher accuracy.

摘要： A processor-implemented method with object tracking includes: determining an initial template image based on an input bounding box and an input image; generating an initial feature map by extracting features from the initial template image; generating a transformed feature map by performing feature transformation adapted to objectness on the initial feature map; generating an objectness probability map and a bounding box map indicating bounding box information corresponding to each coordinate of the objectness probability map by performing objectness-based bounding box regression analysis on the transformed feature map; and determining a refined bounding box based on the objectness probability map and the bounding box map.
