中文摘要：

根据矩形贴片的腔膜理论，以Rogers(5880)作为介质基板材料，设计了中心频点在24GHz的贴片结构，用数值仿真方法进行了研究；按照阻抗匹配和天线增益要求，借助Matlab和ADS软件，设计了功分网络；最后采用HFSS软件对6×14微带阵列天线进行了系统仿真，计算了该天线阵的增益、带宽、电压驻波比、方向图等参数，并在中物院5所微波暗室平台进行测试，各参数都达到要求。

英文摘要：

A microstrip antenna array is designed based on the theory of cavity and mode of rectangular patch.The array is constructed on the Rogers(5880)as dielectric substrate material;and operating center frequency is24GHz.Research is conducted by using electromagnetic simulation software,such as A Dissertation Submitted(ADS),High Frequency Structure Simulator(HFSS),as well as Matrix Laboratory(MATLAB)programming.According to the requirements of antenna's impedance match and gain,a power divider network is also designed.Finally,the microstrip antenna array with6×14units is simulated by using the HFSS software,some core parameters of the array including in gain,bandwidth,voltage standing wave ratio,and emission patterns,are obtained.Fabricated sample is tested in the platform of microwave dark room of Institute of Electronic Engineering in China Academy of Engineering Physics.Results are in very good agreement with requirements.
