Direction of arrival (DoA) is estimated in real-time for the array with spacing d=lambda/4. The decoupling matrix was measured using a VNA for only one incident angle. After compensation the error in DoA estimation was reduced to 5%. Comparing the DoA results with d=lambda/2 spaced Uniform Linear Array (ULA), 1.2% error was observed. Although, the experiment was performed indoors with a low SNR, the results show a substantial improvement in the estimated DoA after compensation.eninfo:eu-repo/semantics/embargoedAccessDirection of ArrivalLabViewMutual CouplingReceiving Antenna ArraysSDRArticle35111433143410.47037/2020.ACES.J.351185Q4Q3
