Hello,

Thanks for your reply. I haven't tried it yet and i will try it now but i have some queries.In most of the example WiFi code there is no option of calling antenna model for nodes.If i just replace that particular constant antenna model will all the nodes will get that antenna model by default? Suppose, if i use wifi-simple-adhoc.cc example code and in that code they have used YansWiFiChannel and in the code there is no option of setting antenna for the nodes, can you please explain that?  I was searching for set antenna option which i can call from script but did not able to find it yet.In addition to that can you send me any directional antenna attached nodes NS-3 code so that i can test either it works similarly with isotropic antenna or not? Thanks again!

Hello,

Thanks for your kind reply. I have gone through the code that is MIMO code so antenna numbers can be added but antenna type can not be set in the code.If i integrate the patch my question is how will i understand about antenna properties like directional(Gain,Radiation Pattern) properties? I am not sure regarding antenna properties and what about propagation modeling?
