As the title says I am doing a project to design an antenna for base stations in mobile communication using CST software. I have attained a very good match at both ports (I have attached a word document with screenshots). The problem I am having is that the total efficiency at the resonant frequency (3.4GHz) is just above 20% when ideally it should be around 70%. I am not sure what the reason for this is I am using FR4 for the substrates and PEC for the ground and patch. There must be some sort of error in the design but I have no idea what it is, I will attach my CST file.
Any help would be greatly appreciated.
