| 摘 要： | 介绍了一种宽带微带贴片天线单元及2元阵列的设计方法，天线工作的中心频率为rl_5OHz（S波段）。天线单元设计中采用口径耦合理论和层叠贴片天线结构，有效增大了天线的阻抗带宽。仿真结果表明该天线阵列实际增益达到11．9dB；在2．27～2．78GHz频率范围内端口驻波比小于2，相对带宽为20．4％；交叉极化电平为-31dB，证明该天线阵具有宽频带、低交叉极化等优良性能。

| Abstract: | A design scheme of microstrip patch antenna element and 2-element array with wide bandwidth application is presented in this paper. The operation frequency of the antenna is 2. 5GHz （S-band）. The aperture-coupled theory and stacked patch antenna （SPA） architecture are adopted in the design of antenna element in ordel to increase the impedance bandwidth. The simulation results show that the realized gain of the array reaches 11.9 dB. The relative impedance bandwidth is 20.4% in frequency domain ranging from 2, 27 GHz to 2.78 GHz when voltage standing wave ratio （VSWR） is less than 2, while the cross-polarization is lower than --31 dB. |
