Antenna radiation characteristics can be modeled by some poles and residues. In this paper, we compare two different methods to extract these poles of a noisy antenna radiation in frequency and in time domain: the Cauchy method and the Total Least Square Matrix Pencil Method respectively. Results are presented for a dipole antenna and an Archimedean spiral antenna.
