微带天线和常用的微波天线相比，有体积小、重量轻、低剖面、易共形等特点。但是他的窄频带特性成了限制其广泛应用的主要障碍，因此，展宽微带天线的带宽具有十分重要的意义。本文通过减小介质介电常数，增大介质厚度，并最终采用双层微带天线的方法，设计了一个60GHz的双层微带天线，拓展带宽到6GHz。

Compared to usual microwave antenna, microstrip antenna has many advantages, such as small size, light weight, low profile and good conformal shape. But its narrow-band characteristic has limited it from widespread application. So broadening the bandwidth of microstrip antenna is very important. In this paper, a double-layer microstrip antenna working at 60GHz is designed . By the way of reducing the dielectric constant and increasing media thickness, and its bandwidth to 6GHz.
