Abstract
A novel methodology for robust near-field (NF) antenna characterization, based on probabilistic sparsity, is proposed. This method leverages the measurements-by-design (MebD) paradigm and incorporates prior knowledge of the antenna under test (AUT) to construct an overcomplete representation basis. Subsequently, a Bayesian strategy is employed to solve the reformulated problem. Representative numerical results are provided to demonstrate the efficacy of our approach in reducing the burden/cost of the acquisition process and mitigating potential truncation errors.
