Abstract :
It is shown that a log-periodic dipole antenna can be optimized by varying the feed-line characteristic impedance while carrying out swept-frequency far-field and impedance measurements. The minimization of narrow-band anomalies in the measured quantities results in a well-defined optimum characteristic impedance.
