COMPACTED PATCH ANTENNA
First Claim
1. A compacted patch antenna, particularly for installation in a vehicle, comprising an electrically supplied strip radiating element, a ground plane to which said strip radiating element is connected at a first end by means of metal link and at a second end, opposite to the first end, by means of a variable capacitor, a printed circuit the bottom surface of which is integral with the ground plane, a dielectric material layer arranged between the strip radiating element and the printed circuit, said strip radiating element being substantially parallel to said ground plane, characterized in that said dielectric material layer has a relative dielectric constant ranging from 3 to 6 and a loss factor ranging from 0.03 to 0.1.

Abstract
A compacted patch antenna is described, particularly for installation in a vehicle, comprising an electrically supplied strip radiating element and a ground plane. The strip radiating element is connected to the ground plane at a first end by means of a metal link and at a second end, opposite to the first end, by means of a variable capacitor. The compacted patch antenna comprises a printed circuit, the bottom surface of which is integral with the ground plane, a dielectric material layer arranged between the strip radiating element and the printed circuit; the strip radiating element is substantially parallel to the ground mass. 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.
