Antenna

The invention discloses an antenna, which comprises a columnar outer shell and a lengthwise circuit board accommodated in the outer shell, wherein the circuit board is provided with a first conducting sheet, a second conducting sheet and a third conducting sheet which are arranged at intervals, the first conducting sheet comprises a main body part, a first vertical part and a first bending part, the first vertical part vertically extends downwards from one end of the main body part, the first bending part transversely bends and extends, the main body part controls a 5GHz current path, and the first bending part controls a 2.4 GHz current path, so that the antenna has dual-frequency and high-gain performance at the same time. 本发明公开了一种天线，其包括柱状的外壳体及收容于外壳体内的纵长电路板，所述电路板上设有间隔设置的第一导电片、第二导电片及第三导电片，所述第一导电片包括主体部、自所述主体部一端分别向下竖直延伸的第一竖直部以及横向弯折延伸的第一弯折部，所述主体部控制5GHz电流路径，所述第一弯折部控制2.4GHz电流路径。从而使天线在兼具双频的同时，还可以达到高增益的性能。
