There is a option in CST in farfield plot called Array. It helps to predict farfield calculation of antenna arrays from your single element. I am using single patch to predict plot for 8 elements in vertical array.
Problem: When I doubled the amplitude(2A) for each antenna element the gain remained the same as was in single amplitude(A) to each antenna element.
Question:
1. As far as I know the total gain should increase with increase in amplitude to each element. Is this some issue of CST where it is re-scaling results or is it because of physics that I should know?
2. I want to understand the behavior of beam with change in magnitude to each element. Is there some pre defined pattern with change in magnitude?
