| 摘要 |
The invention concerns a resonant cavity antenna having a beam conformed according to a predetermined radiation diagram and comprising: a resonant cavity (21; 31) especially having a lower face and an upper face and consisting of a dielectric substrate (22; 32) covered respectively on the bottom and top faces thereof with a network of semi-reflective patterns (24, 23; 34, 33); excitation means (25; 35) of said resonant cavity in said bottom face for a radiating source; optionally, at least one layer consisting of a dielectric buffer substrate (26) located between the bottom face of said resonant cavity and the aforementioned excitation means. According to the invention, said resonant cavity is a flat plane cavity, the top and bottom faces of the dielectric substrate of said resonant cavity being flat and substantially parallel relative to one another. |
