Abstract :
This paper studies, from the point of view of the traveling-wave approach, the transient radiation by V-antennas including the dependence of the maximum directivity on the interior angle, on the length of the arms and on the characteristics of the exciting pulse. As particular examples, the cases when the antenna is excited by a harmonic signal and a Gaussian pulse are analyzed and the results obtained using the traveling-wave approach are compared with the ones obtained using numerical methods
