backfire antenna

antenne rétrodirective

électronique et électrotechnique - iate.europa.eu

The presence of the cavity and accommodating some of the length of the balun in the cavity allows a reduction in the size and weight of a dielectrically loaded backfire antenna.

La présence de la cavité et la possibilité de loger une certaine longueur du symétriseur d’antenne dans la cavité permet de réduire la taille et le poids d’une antenne rétrodirective à charge diélectrique.
