| 摘 要： | 基于漏波波导行波天线辐射理论，设计了一种X波段基于漏波波导的高功率微波（HPM）天线。采用微扰法和横向谐振法对天线的辐射特性进行分析，结合数值模拟优化给出了一种基于漏波波导的X波段HPM天线的设计方案。数值模拟表明:该天线在9.6 GHz时增益为26.2 dBi，口径效率大于70%，反射系数小于-20 dB。通过理论分析与数值模拟得到该天线的功率容量大于200 MW，在最大增益点上对ns量级短脉冲的远场响应波形不存在畸变，验证了该天线在HPM条件下使用的可行性。

| Abstract: | An X-band high power microwave(HPM) antenna based on leaky waveguide was designed and investigated.Its radiation characteristics were determined by transverse resonance approach and numerical full wave simulation optimization.The simulation results indicate that,the antenna gain is 26.2 dBi,the aperture efficiency is above 70%,the power handling capacity is above 200 MW at 9.6 GHz,the reflection coefficient is less than-20 dB,and in far-field waveform deformation would not occur at the angle of maximum radi... |
