Enhancing Gain Through Optimal Antenna Element Distribution in a Thinned Array Configuration
IEEE Open Journal of Antennas and Propagation, 2023 This paper presents an array thinning approach for a 25-element antenna array arranged in a $5\times5$ grid at 5.4 GHz. Our goal is to eliminate a maximum number of antenna elements with minor gain loss and hence reduce the array size, weight, cost ...

Optimized Multi-Level Prime Array Configurations [PDF]
2021 International Symposium on Networks, Computers and Communications (ISNCC), 2021 Antenna arrays have many applications in direction-of-arrival (DOA) estimation. Sparse arrays such as nested arrays, super nested arrays, and coprime arrays have large degrees of freedom (DOFs). They can estimate large number of sources greater than the number of elements.
