摘要
设计制作了一款新结构的垂直极化全向微带天线。天线利用分布于立方体侧面上的四个对称性天线单元的单向辐射实现全向辐射,通过单元辐射结构上加载两臂,增加天线的谐振点,展宽设计天线的带宽,对该天线进行了仿真和测试。结果表明,仿真与测试结果基本吻合。设计的天线带宽覆盖了1.7~2.8 GHz,反射系数S11〈–10 d B的相对带宽达到49%,在整个频带内实现了全向辐射。天线结构简单且紧凑,易于加工,可用于移动通信领域。
A novel kind of vertically polarized omnidirectional microstrip antenna was designed and fabricated. By combining the four symmetry unidirectional radiation antenna elements on the side surface of the cube to achieve omnidirectional radiation, using the loading arms of the rectangular radiating structure of the antenna element to increase the resonance point of the antenna, the bandwidth of the antenna was broadened. The antenna was simulated and detected. Results show that the test results and simulation results can coincide each other basically. The bandwidth of the antenna covers the whole frequency range in 1.7-2.8 GHz, the relative bandwidth of S11〈–10 dB reaches 49%, the antenna achieves an omnidirectional radiation over the entire frequency band, and its structure is simple and compact, easy to process, it can be used for the mobile communications.
