| 摘要 |
<p>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.</p> |
