1. A multipatch antenna comprising:
- an array of at least substantially equal radiators, positioned on one side of a dielectric sheet;
a conductive ground plane positioned on the other side of the dielectric sheet;
feeding means positioned near the ground plane on a side facing away from the dielectric sheet; and
capacitive coupling means incorporated between the feeding means and the radiators for energizing the radiators;
wherein the radiators each consist of one single radiating patch, positioned on an outer surface of the dielectric sheet and the capacitive coupling means comprise constant diameter conducting probes, on one side connected to the feeding means and on the other side ending in the dielectric sheet near the radiating patch, such that the ends of the conducting probes are completely embedded in the dielectric sheet.

Abstract
A multipatch antenna including radiating patches (2) positioned on a dielectric sheet (1). The patches (2) are capacitively fed by probes (7) ending in the dielectric sheet (1) near the patches (2). By positioning the probes (7) near selected edges of the radiating patches (2), a selected polarization direction of the radiation field can be realized. By positioning several probes (7) near a radiating patch (2), a radiation field with an adjustable polarization direction or a radiation field with an extremely low cross-polarization can be obtained.
