摘　　要：为了使矩形微带天线的实际谐振频率和设计频率相一致,矩形贴片元物理尺寸的精确计算是非常重要的。文中在腔模理论的基础上,计入辐射损耗,提出了一种精确计算毫米波矩形微带天线贴片元物理尺寸的新方法,并利用该方法计算设计了四元毫米波矩形微带贴片天线,仿真和实测结果证实了该方法的有效性。In order to make actual resonance frequency consistent with designed frequeney of rectangular microstrip antenna, accurate calculation of rectangular patch element physical size is very important. Based on the cavity model theory, this article presented an innovative method which took into account the radiation loss, to accurately calculate the patch length and width of MM - wave rectangular microstrip antenna. The method was applied to design a four - element MM - wave rectangular microstrip patch antenna. Both the simulation and actual measurement results proved the effectiveness of the present method.
