利用matlab对矩形贴片天线进行建模

分享一下编写程序，获取贴片天线的回波损耗、VSWR、-10dB带宽。过程中有不懂的欢迎交流。

%介质基层尺寸，单位m，**e-3单位mm，根据自己的设计进行填充各值
subThickness =**;
subLength = **;
subWidth = **;

%接地板尺寸
gndLength =**;
gndWidth = **;

%辐射贴片尺寸
patchLength = **;
patchWidth = **;

%馈线尺寸
feedlineLength = **;
feedlineWidth = **;

%切割尺寸
patchcutLength = **;
patchcutWidth = **;

%定义介质基层材料
sub = dielectric("Name",{'FR4'},"EpsilonR",4.4,"Thickness",subThickness);

%创建辐射贴片
Patch  = antenna.Rectangle("Length",patchWidth,"Width",patchLength,"Center",[0,patchLength/2-(subLength/2-feedlineLength)]);

%创建接地板
Gnd = antenna.Rectangle('Length',gndWidth,'Width',gn
