Hello, Good day. I have a question about gain and radiation efficiency in the interest of frequency region. According to S11, my interest in frequency bands ranges from 3.24 GHz to 8.74 GHz. However, if you look at the gain vs frequency graph, it drops after 3.24 GHz and then rises. The same thing happened in the radiation efficiency graph.I'm not sure why this is happening; do you have any ideas about the graph's behavior?
Many thanks for considering my request.

It is expected for the results of Radiation efficiency and Gain to have this behavior.
The Radiation Efficiency and Gain are calculated using the Accepted Power. Accepted Power is calculated using the s11 parameter.
