Antenna

The utility model relates to an antenna which comprises a first radiating body and a second radiating body, the first radiating body is used for being connected with a feeding point, the second radiating body is used for being connected with a grounding point, the interior of the second radiating body is hollow, the first radiating body is arranged in the second radiating body, and the first radiating body and the second radiating body are mutually insulated. The second radiator is of a hollow structure with two open ends and a closed periphery, the two open ends of the second radiator are opposite in the front-back direction, and electromagnetic waves can pass through the two open ends of the second radiator. The antenna can realize bidirectional radiation of signals and has the advantage of high gain. 本公开涉及一种天线，该天线包括第一辐射体和第二辐射体，第一辐射体用于与馈电点连接，第二辐射体用于与接地点连接，所述第二辐射体的内部中空，所述第一辐射体设置在所述第二辐射体内并与所述第二辐射体相互绝缘，所述第二辐射体形成为两端开放且四周封闭的中空结构，所述第二辐射体的两个开放端沿前后方向相对，所述第二辐射体的两个开放端能够供电磁波通过。上述的天线能够实现信号的双向辐射，且具有高增益的优点。
