Abstract
The goal of the paper is to improve the log-periodic dipole antenna (LPDA) design procedure introduced by Carrel (1961). A computer-aided design technique is introduced, providing an easy-to-use design method of LPDAs. Corrections to Carrel´s design contours, and new constant input resistance and truncation coefficients diagrams are presented. The influence of the feeder characteristic impedance, and dipole length-to-diameter ratio on LPDA parameters is studied. Design diagrams for LPDA´s typical of HF communications are included.
