Optimization of antenna arrays for 2D DoA estimation using EADF for Cramér-Rao Lower Bounds computation

This paper presents results on optimization of antenna arrays to be used for Direction of Arrival (DoA) estimation using Cramér-Rao Lower Bounds computation. In our work, we apply the optimization to an L-quad antenna array and to a nonuniform patch array and compare the results in terms of direction finding capability. The aim of the optimization procedure is to increase the DoA estimation ability for the most compact antenna array the possible without losing focus on the antenna radiation constraints.
