Abstract (en)
[origin: EP0542595A1] An antenna comprises a first dielectric layer (D1) including on one side an earth-plane (PM1), and on the other a first conductive slab (P1) of chosen shape. A second dielectric layer (D2) surmounts the first on the first slab side, and supports, on the other side, facing the first slab, a second conductive slab (P2) of chosen shape. A third dielectric layer (DR) surmounts the second. The second slab (P2) is of smaller size than that of the first slab (P1), and this first slab (P1) is fed from the bottom, at at least one chosen point (FR1) situated between its centre and its periphery. Advantageously, the first slab (P1) is connected to a run-through (TR1) of the first-plane joining up with a feed circuit (DL1, DL2) implanted in the dielectric substrate of three-plate structure (SDH, SDB). <IMAGE>
