The DGS is implemented by etching circular holes in the ground plane of the patch antenna.

通过在贴片天线地板上刻蚀圆孔实现DGS结构。

Planar slot antenna is proposed firstly, simplifying the surface of the airplane to be a large mental plane which inclines against the ground plane.

方案一采用介质微带缝隙天线的形式，简便起见，简化机体表面模型为一倾斜放置的超大金属平面。

Resonant frequency can be changed by loading the antenna with a reactive tuning component, which can be placed between the antenna element and the ground plane.

共振频率可以改变被动的加载与调谐组件，它可与天线单元和接地层放置天线。
