AN EXAMINATION OF THE EFFECT OF MECHANICAL DEFORMATION ON THE INPUT IMPEDANCE OF HF LPDA'S USING MBPE

Abstract

This article examines the application of Model Based Parameter Estimation (MBPE) to the evaluation of the input impedance of HF Log Periodic Dipole Arrays (LPDA) during mechanical deformation. A study of cases of lengthening, shortening and displacing one element as well as the effect of mechanical sagging of the array is made. It is found that MBPE is a useful tool for minimizing computations and/or measurements in the study of mechanical deformation.
