| 摘要 |
The invention relates to an antenna that is particularly useful in stations for testing electromagnetic fields. The antenna has a predetermined operating frequency, corresponding to a predetermined wavelength, wherein said antenna includes : a conductive sectoral horn (2) one open end of which (6) is built into a floorplan (8); short-circuited radiating slots (10, 12), built into the floorplan, on either side of said open end; and conductive louvres (22, 24), arranged above the slots and said open end, and capable of being deployed mechanically in a continuous manner in order to modify the radiation pattern of the antenna. |
