| 摘要 |
A compacted patch antenna is described, particularly for installation in a vehicle, comprising an electrically supplied strip radiating element (1) and a ground plane (3), The strip radiating element is connected to the ground plane at a first end (11) by means of a metal link and at a second end (12), opposite to the first end, by means of a variable capacitor (5). The compacted patch antenna comprises a printed circuit (2), the bottom surface of which is integral with the ground plane (3), a dielectric material layer (6) arranged between the strip radiating element (1) and the printed circuit (2); the strip radiating element (1) is substantially parallel to the ground mass (3). The dielectric material layer has a relative dielectric constant ranging between 3 to 6 with a loss factor ranging between 0.03 to 0.1.
