The DGS is implemented by etching circular holes in the groundplane 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 groundplane.
