【摘要】 为实现工作在毫米波频段的大角度扫描阵列,本文设计并实现了一种基于SIW背腔的宽波束微带天线。仿真结果表明:该天线的-15d B阻抗带宽为23.5GHz～30.26GHz,覆盖了5G毫米波频段n257(26.5GHz～29.5GHz)以及n258(24.25GHz～27.5GHz)。该天线的半功率波束宽度在工作带宽内均大于110度。在电磁仿真的基础上,进行了天线实物加工测试,测试结果与设计结果基本一致。更多还原

【Abstract】 In order to realize a wide-angle scanning array working in millimeter wave, a wide-beam substrate integrate waveguide cavity-backed slot antenna is proposed in this paper. The simulation results show that the-15 dB impedance bandwidth of the antenna is 23.5 GHz～30.26 GHz, covering the 5G millimeter wave frequency bands n257(26.5 GHz～29.5 GHz) and n258(24.25 GHz～27.5 GHz). The half-power beamwidth of the antenna is greater than 110 degrees within the working bandwidth. On the basis of electromagnetic simulation, the antenna prototype was designed and mesuared, and the measured results are basically consistent with the simulation results.更多还原
