Hi to all the experts out there!:grin:
I have simulated a simple 30MHz monopole antenna with an infinite ground plane and using pec as the material. I have specified my source impedance to be 50ohms. However, I realised my radiation pattern plot has a high realised gain of 5.4694dB at the 90deg direction. I wonder why the antenna has such a high value as compared to the typical 5.15dB, as this means that my simulation is not really accurate. Please kindly enlighten me on my mistake!
Thank you very much.
