This article proposes and designs a multi‐band antenna that imitates banana leaves structurally. The edge structure of the antenna radiator is a mirror‐symmetrical trapezoid, and four patches of different sizes are used as leaf veins inside. The feeding mode is coplanar waveguide feeding with a trapezoidal structure. The electromagnetic simulation software HFSS is used for antenna modeling and parameter optimization. The test results show that the antenna can cover 0.79 to 3.18 GHz, 3.29 to 3.98 GHz, and 4.98 to 7.62 GHz and produce six main frequency points: 0.9, 1.5, 2.4, 3.8, 5.6, and 6.9 GHz. The antenna has omnidirectional radiation characteristics and can be widely used in the future mobile communication network coverage field.

用于移动终端的多频带仿生天线的设计

本文提出并设计了一种在结构上模仿香蕉叶的多频带天线。天线辐射器的边缘结构为镜面对称梯形，内部使用了四个大小不同的贴片作为叶脉。馈电模式是具有梯形结构的共面波导馈电。电磁仿真软件HFSS用于天线建模和参数优化。测试结果表明，该天线可以覆盖0.79至3.18 GHz，3.29至3.98 GHz和4.98至7.62 GHz并产生六个主要频率点：0.9、1.5、2.4、3.8、5.6和6.9 GHz。该天线具有全向辐射特性，可广泛应用于未来的移动通信网络覆盖领域。
