- 提出一种工作在X波段的低副瓣波导缝隙天线,采用泰勒综合法对波导缝隙天线的方向图进行赋形,使用电磁仿真软件HFSS优化天线口径、缝隙单元的数量和偏移量等参数。结果表明,天线频率在9.09～9.63 GHz回波损耗优于-10 dB,增益大于16 dB,副瓣电平低于-25 dB,天线效率达到81%。测量和仿真结果吻合较好,证明了设计方法的有效性。
- Abstract:
- A low-sidelobe waveguide slot antenna operating at the X-band is proposed.The Taylor synthesis method is used to shape the pattern of the waveguide slot antenna,and the parameters such as the antenna aperture,the number of slot elements,and the offset are optimized using HFSS tools.The measured results show that the antenna has a return loss better than 10 dB,and a gain of more than 16 dB,a sidelobe level of less than -25 dB within the frequency range of 9.09-9.63 GHz.The efficiency of the antenna is approximately 81%.The measured results and the simulated ones agree well,proving the effectiveness of this design method.
