Title
(EN) SLOT ARRAY ANTENNA
(FR) ANTENNE A FENTES
Abstract
(EN)
A thin, low-loss, and two-frequency slot array antenna which excites slot elements having different resonance frequencies through a common parallel-plate waveguide and radiates the same linearly polarized wave at different frequencies. The slot array antenna comprises the slot elements having different resonance frequencies and arranged on one conductor plate of the parallel-plate waveguide having short faces at both ends in such a way that the directions of the electric fields of the slot elements are perpendicular to the short faces.
(FR)
L'invention concerne une antenne à fentes mince, à faibles pertes et à deux fréquences, qui excite des éléments fente ayant différentes fréquences de résonance à travers un guide d'ondes à plaques parallèles commun, et qui émet la même onde polarisée de manière linéaire à différentes fréquences. L'antenne à fentes comporte ces éléments fente qui ont différentes fréquences de résonance, et qui sont pratiqués sur une plaque conductrice du guide d'ondes à plaques parallèles ayant des faces courtes aux deux extrémités, de sorte que les directions des champs électriques des éléments fente sont perpendiculaires aux faces courtes.
