Sensitivity of the singularity expansion method applied on dipole antenna backscattering
Résumé
This paper deals with the sensitivity of the singularity expansion method to identify antennas. A dipole antenna is considered and the matrix pencil method is applied on its backscattered field. Then, small variations of length, diameter and load impedance are applied on the dipole antenna and the variation of poles in the complex plane is analyzed. It shows that pole extraction is very sensitive to the dimensions and load impedance of the narrow band dipole antenna.
