  New constraints based on practical hardware are introduced in compressive
sensing (CS) based rectangular antenna array thinning technique. In a standard
CS array sparsity enforcement, antenna elements are considered as ideal point
sources which do not comply with the practical hardware. It also does not
consider the impact of mutual coupling of neighbouring antenna elements on the
impedance mismatch. In this work, we propose a combination of constraints based
on physical antenna array specifications, mutual coupling and practical antenna
element radiation performance in the CS-based array thinning enforcement.
Analytical modelling along with a design example is presented and discussed.
Array performance based on full-wave electromagnetic simulations shows the
reliability of the proposed approach.
