摘　　要：C波段(3.4~3.6 GHz)的频段作为5G初期部署的核心主力,满足了5G业务连续性、覆盖、用户移动性及容量等基本需求。同时,微带天线具有体积小、重量轻、制造工艺简单、易于共形等优点。为了满足C波段需求,充分发挥微带天线优势,设计了一种工作频率为3.5 GHz的矩形微带天线。利用HFSS15.0软件对该天线进行建模仿真,结果表明,该矩形微带天线的频率为3.5 GHz,回波损耗约为-29.8 dB,电压驻波比约为1.06,阻抗匹配良好,增益在3.15 dB左右,且微带天线尺寸较小,达到了C波段的矩形微带天线的设计要求。The C-band （3.4 to 3.6 GHz）, as the core of the initial deployment of 5G, could satisfy the basic needs of 5G service continuity, including coverage, user mobility and capacity. In addition, the microstrip antenna has the advantages of small size, light weight, simple manufacturing process and easy conformality. In order to meet the C-band requirements and take full advantage of the microstrip antenna, a rectangular microstrip antenna operating at 3.5 GHz is designed. The antenna was modeled and simulated with HFSS15.0 software. The experiment results indicate that the frequency of the rectangular microstrip antenna is 3.5 GHz, the return loss about -29.8 dB, and the voltage standing wave ratio about 1.06, while the impedance matching is good, the gain about 3.15 dB, and the size relatively small, meeting the design requirements of the C-band rectangular microstrip antenna.
