A compact dual mode wideband antenna is presented in this paper which operates from 24.8 to 31.6 GHz (suitable for 5G applications). The antenna is based on substrate integrated waveguide (SIW) and consists of a two‐element array of half‐bow‐tie slots. Each slot excites two modes (slot mode and half patch mode) in the antenna due to its geometry. The resonant frequencies in these modes are optimized to achieve wide impedance bandwidth using Ansys HFSS. A prototype is fabricated and its measured impedance bandwidth is 6.8 GHz, which is in close agreement with the simulated one. It also has a peak gain of 8.5 dBi at 30.4 GHz and its physical size is 2.4λg × λg, where λg is the guide wavelength at center frequency.

适用于5G应用的双模宽带SIW缝隙天线设计

本文介绍了一种紧凑型双模宽带天线,其工作频率为24.8至31.6 GHz(适用于5G应用)。该天线基于基片集成波导(SIW),由半弓形缝隙的两元素阵列组成。每个缝隙由于其几何形状而在天线中激发两种模式(缝隙模式和半贴片模式)。使用Ansys HFSS对这些模式下的谐振频率进行了优化,以实现宽阻抗带宽。制作了一个原型,其测量的阻抗带宽为6.8 GHz,与仿真的阻抗带宽非常吻合。它也有8.5 dBi的的峰值增益在30.4 GHz和它的物理尺寸为2.4 λ ×  λ,其中λ是在中心频率波导波长。
