English: Animation of a half-wave dipole antenna transmitting radio waves, showing the electric field lines. The dipole, in the center, consists of two vertical metal rods with an alternating current at its resonant frequency applied at its center from a radio transmitter (not shown) The voltage alternately charges the two ends of the antenna positive (+) and negative (−). Standing waves of current (red arrows) flow up and down the rods. The alternating voltage on the rods creates loops of electric field (black lines) that pinch off into closed loops and radiate away from the antenna at the speed of light. These are the radio waves. The radiated power is greatest in the horizontal direction, perpendicular to the antenna, and decreases to zero above and below the antenna, on the antenna axis. This picture only shows the electric field in a single plane through the antenna axis; the field is actually axially symmetrical about the antenna. The action is shown slowed down drastically in this animation; real radio waves oscillate at rates of thirty thousand to a billion cycles per second. Français : Animation d'une antenne dipôle demi-onde transmettant des ondes radio, montrant les lignes de champ radioélectrique . Le dipôle, au centre, est constitué de deux tiges métalliques verticales avec un courant alternatif à sa fréquence de résonance appliqué en son centre par un émetteur radio non représenté. La tension charge alternativement les deux extrémités de l'antenne positive (+) et négative ( -). Les vagues de courant stationnaire (flèches rouges) circule de haut en bas sur les tiges. La tension alternative sur les tiges crée des boucles de champ électrique (lignes noires) qui se pincent en boucles fermées et rayonnent loin de l'antenne à la vitesse de la lumière. Ce sont les ondes radio. La puissance rayonnée est la plus grande dans la direction horizontale, perpendiculaire à l'antenne, et diminue jusqu'à zéro au-dessus et au-dessous de l'antenne, sur l'axe de l'antenne. Cette image montre seulement le champ électrique dans un seul plan à travers l'axe de l'antenne; le champ est en réalité axialement symétrique par rapport à l'antenne. L'action est montrée ralentie de façon drastique dans cette animation; les vraies ondes radio oscillent à des rythmes de trente mille à un milliard de cycles par seconde. |
