摘　　要：基于PCB过孔镜像技术,设计优化了5G多频段微带天线。近似电壁边界的短路孔镜像天线辐射单元,减小天线结构尺寸;近似电容元件的开路孔起调谐作用,有效调谐回波损耗。在工作频带内多峰振荡,方向图较为稳定,带内增益平均6dBi以上,回波损耗低于-10 dB。在预设观察模式和频点下确定天线结构及尺寸,采用电磁模拟仿真的方法,降低回波损耗,优化方向图等指标。With the continuous improvement of UWB technology,it has become more and more widely used as the antenna design of the key units of the system.In this paper,a microstrip antenna（3.3-3.6,4.8-5.0 GHz） is designed,and the antenna structure size is effectively reduced by the antenna design based on the PCB via hole technology.In the observation mode and frequency points,the antenna structure and size are determined,and the antenna reflection coefficient and the direction chart are analyzed by using the method of electromagnetic simulation.In the working band,several peak oscillations are realized,the direction chart is stable,the average of the gain is 6 dBi,and the return loss is lower than -10 dB.
