本文描述了用于自适应5G网络的双频开槽波导天线阵列的设计、仿真和测量，该天线阵列工作在毫米波频率范围内。它的结构是由两组槽铣在一个矩形波导的相对面，使天线工作在两个不同的频段，即28和38 GHz。使用ANSYS HFSS获得的测量和数值计算结果表明，28 GHz和38 GHz的两个带宽分别约为26.36%和9.78%。天线增益从低频带的12.6 dBi变化到高频带的15.6 dBi。
This paper describes the design, simulation and measurement of a dual-band slotted waveguide antenna array for adaptive 5G networks, operating in the millimeter wave frequency range. Its structure is composed by two groups of slots milled onto the opposite faces of a rectangular waveguide, enabling antenna operation over two different frequency bands, namely 28 and 38 GHz. Measured and numerical results, obtained using ANSYS HFSS, demonstrate two bandwidths of approximately 26.36% and 9.78% for 28 GHz and 38 GHz, respectively. The antenna gain varies from 12.6 dBi for the lower frequency band to 15.6dBi for the higher one.
