Cet article présente les caractéristiques de base d'une antenne dipôle EMI de type à résonance forcée pour les fréquences inférieures à 80 MHz dans laquelle deux éléments de réactance sont utilisés pour l'adaptation d'impédance au point d'alimentation. L'impédance d'entrée du dipôle court inférieure à la demi-longueur d'onde est contrôlée par la position de chargement correctement déterminée et la valeur de la réactance de chargement. L'équation intégrale pour la distribution de courant inconnue est résolue par la méthode des moments de Galerkin avec des fonctions sinusoïdales par morceaux. Les résultats numériques montrent que l'antenne dipôle EMI de petite taille avec des facteurs d'antenne inférieurs pour les fréquences inférieures à 80 MHz peut être réalisée par la charge de réactance. Dans le cas où l'antenne dipôle EMI de petite taille à entraînement central proposée avec une longueur de 0.3 λ est chargée c= 0.133 λ à partir du centre, l'impédance d'entrée est adaptée à la ligne d'alimentation avec 50 Ω, et donc l'antenne a des facteurs inférieurs dans la plage de fréquences de 30 à 80 MHz. Les caractéristiques d'atténuation de site normalisées sont également présentées pour l'antenne dipôle EMI de type à résonance forcée.

Abstract: This paper presents the basic characteristics of a forced resonant type EMI dipole antenna for frequencies below 80 MHz in which two reactance elements are used for the impedance matching at the feed point. The input impedance of the short dipole less than half-wavelength is controlled by the properly determined loading position and the value of loading reactance. The integral equation for unknown current distribution is solved by Galerkin's method of moments with piecewise sinusoidal functions. The numerical results show that the small-sized EMI dipole antenna with lower antenna factors for frequencies below 80 MHz can be realized by the reactance loading. In case the proposed center driven small-sized EMI dipole antenna with 0.3λ length is loaded c=0.133λ from the center, the input impedance is matched at feed line with 50 Ω, and hence the antenna has lower factors in the frequency range of 30 to 80 MHz. Also the normalized site attenuation characteristics are presented for the forced resonant type EMI dipole antenna.
