| 摘 要： | 设计、制作并测量了基片集成波导（SIW） E面和H面（平面）混合功分器馈电的2×4印刷宽带对数周期天线阵列，并与1×4印刷宽带对数周期天线阵列进行了测试比较。实测1×4印刷对数周期天线阵列在10.5~19.5 GHz内回波损耗小于-10 dB，2×4印刷对数周期天线阵列在11.2~16.7 GHz内回波损耗小于-10 dB.文中给出了1×4和2×4印刷对数周天线阵列在12 GHz、13 GHz、14 GHz、15 GHz和16 GHz的实测辐射方向图和两个阵列天线带内的辐射增益。测试结果表明：2×4印刷对数周天线阵列在工作频带内辐射特性稳定，增益比1×4印刷对数周天线阵列提高1~3 dB.

| Abstract: | In the paper, a 2×4 printed log periodic antenna array fed by an E/H-plane hybrid power divider is presented and compared with 1×4 printed log periodic antenna array. The measured impedance bandwidth of the 1×4 printed log periodic antenna array is 10.5~19.5 GHz for|S11| ≤ -10 dB. The measured impedance bandwidth of the 2×4 printed log periodic antenna array is 11.2~16.7 GHz for|S11| ≤ -10 dB. The measured radiation patterns of the 1×4 and 2×4 antenna array at 12 GHz, 13 GHz, 14 GHz, 15 GHz and 16 GHz are presented. The 2×4 printed log periodic antenna array has the similar radiation characteristics in the working bandwidth and the radiation gain is improved by 1~3 dB compared with 1×4 printed log periodic antenna array. |
