Abstract

This letter introduces an interpolation and bandlimited signal extrapolation method to reconstruct the non-uniformly distributed samples with sampling intervals larger than λ₀/2. The proposed method saves the time cost compared with the conventional measurement (sampling interval smaller than λ₀/2). Besides, the truncation errors are decreased, and the testing accuracy is improved. Therefore, the proposed method is accurate and efficient for planar near-field measurements of mm-wave antennas.
