Title (EN) PLANAR ORIENTABLE ANTENNA OPERATING IN THE MICROWAVE BAND
(FR) ANTENNE ORIENTABLE PLANE, FONCTIONNANT EN MICRO-ONDES
Abstract:
(EN) The invention relates to a microwave planar antenna whose main lobe is orientable by mechanical means. A microwave antenna is formed by a network of radiating dipoles (2, 16) arranged in a circuit (3, 4, 17, 18) deposited on a substrate (7), and by a ground plane (8). In order to orient said antenna, at least one dielectric sheet (9) is introduced between the network and the ground plane. Said sheet is comprised of diphasing elements (13, 14, 19, 20), moulded in the sheet (9). The displacement of the sheet (9) with respect to the network (2, 16) causes a phase shifting of the dipoles and an orientation of the antenna lobe. Application to microwave telecommunication antennas.
(FR) L'invention concerne une antenne plane micro-ondes, dont le lobe principal est orientable par des moyens mécaniques. Une antenne micro-ondes est formée par un réseau de dipôles rayonnants (2, 16) formés en un circuit (3, 4, 17, 18) déposé sur un substrat (7), et par un plan de masse (8). Pour orienter cette antenne, au moins une feuille (9) diélectrique est introduite entre le réseau et le plan de masse. Cette feuille comporte des éléments déphasants (13, 14, 19, 20), moulés dans la feuille (9). Le déplacement de la feuille (9) par rapport au réseau (2, 16) entraîne un déphasage des dipôles, et une orientation du lobe de l'antenne. Application aux antennes de télécommunications micro-ondes.
