| 摘 要： | 为了设计一种结构简单、可靠性高的全向天线，提出了一种基于半模基片集成波导技术的漏波天线.这种天线是在半模基片集成波导结构的H壁增加4个对称振子形成的漏波辐射结构.使用电磁仿真软件对提出的天线结构进行了精确的建模，分析了介质厚度对天线带宽的影响，并对天线结构进行了优化，最后制作了天线测试样片进行实验验证.所设计的天线具有较宽的带宽和准全向辐射的特性，在7.3~9.7 GHz频段内具有良好的辐射性能，最大增益为5.8 dBi，测试结果验证了设计的有效性． |

| Abstract: | In order to design an omnidirectional antenna with simple structure and high reliability， a novel Half Mode Substrate Integrated Waveguide （HMSIW） leak-wave antenna array formed by series arranged dipoles at H wall of HMSIW was presented. The antenna was modeled by using a full-wave electromagnetic simulator. The influence of medium thickness on antenna bandwidth was analyzed and the antenna structure was optimized. Then the antenna was fabricated through a single-layer Printed Circuit Board （PCB） process to verify the design. Wide bandwidth and quasi-omnidirectional radiation pattern were obtained. The proposed antenna kept good radiation performance at 7.3-9.7 GHz frequency range and the gain reached 5.8 dBi. Measured results show the effectiveness of the proposed approach． |
