Multi-band antenna

多频天线

Abstract

The utility model provides a multi-band antenna, which comprises a substrate, a ground plane arranged on the substrate, a first radiation path, a second radiation path, a third radiation path, a connecting path and a short circuit path, wherein the first radiation path, the second radiation path, the third radiation path, the connecting path and the short circuit path are arranged on the substrate. The first radiation path is provided with a first end and a second end, the connecting path is formed by extending of the first end of the first radiation path, and the second radiation path and the third radiation path are both formed by extending of the end of the connecting path. Two ends of the short circuit path are respectively electrically connected with a short circuit point and the first end of the first radiation path, the second radiation path resonates in a first operating band, the first radiation path, the connecting path and the third radiation path resonate in a third operating band, and the free end of the third radiation path is coupled with the second end of the first radiation path so as to resonate in a second operating band.
本实用新型提供一种多频天线,包含:一基板,一设于基板上的接地面,设于基板上的第一、第二、第三辐射路径、连接路径及短路路径,第一辐射路径具有第一端及第二端;连接路径由第一辐射路径的第一端所延伸成型;第二辐射路径与第三辐射路径均由连接路径的末端延伸成型;短路路径的两端分别电性连接于短路点与第一辐射路径的第一端,第二辐射路径共振于第一操作频带,第一辐射路径、连接路径及第三辐射路径共振于第三操作频带,而第三辐射路径的自由端耦合于第一辐射路径的第二端以共振于第二操作频带。
