Antenna module

The invention provides an antenna module. The antenna module comprises a hollow cylindrical conductor structure. The hollow cylindrical conductor structure comprises a cylindrical wall, at least one first slot and a first feed-in point, wherein the at least one first slot and the first feed-in point are located on the cylindrical wall. The cylinder wall comprises a first end edge and a second end edge which are opposite to each other, and at least one first slot extends from the interior of the cylinder wall to the first end edge and forms a first closed path together with the first end edge. The first feed-in point is located beside the at least one first slot. The antenna module is suitable for exciting a first frequency band through the first closed path. 本发明提出一种天线模块。天线模块包括一中空筒状导体结构。中空筒状导体结构包括一筒壁、至少一第一槽缝及一第一馈入点，其中至少一第一槽缝及第一馈入点位于该筒壁。筒壁包括相对的一第一端缘及一第二端缘，至少一第一槽缝从筒壁内部延伸至第一端缘，而与第一端缘共同形成一第一封闭路径。第一馈入点位于至少一第一槽缝旁。天线模块适于通过第一封闭路径激发出一第一频段。
