Abstract

Millimeter-wave (mmWave) antennas are indispensable components in the fifth-generation (5G) wireless communication systems. With the inherent advantages of integration capability, substrate integrated waveguide (SIW) antenna is an excellent choice for applications in the mmWave frequency bands. However, reflection losses occur at dielectric-filled thin apertures of SIW antennas. These reflections can be overcome by impedance matching between the aperture and the free space. In this study, we introduce an mmWave SIW horn antenna having impedance matching transitions (IMTs) across the horn's aperture width. The designed antenna, operating in the 24-28 GHz band, is simulated with a full-wave analysis tool. The simulation results of the modified SIW horn have been confirmed by the experimental results and shown to be satisfactory. The IMTs result in an enhancement of the front-to-back ratio (FTBR). The modified SIW horn antenna with a novel printed transition achieves sidelobe levels (SLLs) of better than ?9 dB at 27 GHz, with an enhanced FTBR above 15 dB. In the 24?28 GHz band, the antenna has a reflection coefficient variation of better than ?10 dB.

h面SIW喇叭天线，增强了5G应用的前后比

毫米波(mmWave)天线是第五代(5G)无线通信系统中不可或缺的组件。基片集成波导(SIW)天线具有固有的集成能力优势，是毫米波频段应用的理想选择。然而，反射损耗发生在介质填充的SIW天线的薄孔处。这些反射可以通过孔径和自由空间之间的阻抗匹配来克服。在这项研究中，我们介绍了一种毫米波SIW喇叭天线，该天线在喇叭的孔径宽度上具有阻抗匹配转换(IMTs)。设计的天线工作在24- 28ghz频段，用全波分析工具进行了仿真。实验结果与改进后的SIW喇叭的仿真结果相吻合，显示出令人满意的结果。imt可以提高前后比(FTBR)。采用新型印刷过渡的改进SIW喇叭天线在27 GHz时的旁瓣电平(SLLs)优于- 9 dB, FTBR增强到15 dB以上。24小时?在28ghz频段，天线的反射系数变化优于10db。
