天线装置及使用其之可携式电子装置;ANTENNA DEVICE AND PORTABLE ELECTRONIC DEVICE USING THE SAME

摘要

在此揭露一种天线装置，其包含：第一金属构件，其具有第一主表面；第二金属构件，其具有平行于第一主表面的第二主表面；以及天线线圈，其具有垂直于第一主表面和第二主表面的线圈轴，其中，第一金属构件构成安装有天线线圈的可携式电子装置的壳体的至少一部分，至少一个狭缝形成在第一金属构件与第二金属构件之间，天线线圈的内径部分在平面视图中与狭缝重叠，并且狭缝在平面视图中在至少在与天线线圈重叠的区域中具有恒定的宽度。; a second metal member having a second main surface parallel to the first main surface; and an antenna coil having a coil axis perpendicular to the first and second main surfaces, wherein the first metal member constitutes at least a part of a housing of a portable electronic device in which the antenna coil is mounted, at least one slit is formed between the first and second metal members, an inner diameter section of the antenna coil overlaps with the slit in planar view, and the slit has a constant width at least in a region that overlaps with the antenna coil in planar view.
