… In order to formulate an upper bound on spectral efficiency that can be gained through
antenna design, we must make the antenna structure part of the optimization variable. In this …

… Although this result is based on the cosine antenna pattern and a lower bound, later we
will show its accuracy via simulations. Similar to Remark 5, the key tool here is the analytical …
