Planar printed-circuit antenna with short-circuited superimposed elements
First Claim
1. A planar printed-circuit antenna for the transmission and/or reception of microwave signals, comprising:
- a first conductive element or patch substantially parallel to a ground plane, the first patch being a C-patch, such that the first patch corresponds to one half of a folded dipole which would have been cut along an axis of symmetry of the folded dipole, said first patch having an essentially rectangular shape with a first side essentially parallel to said axis of symmetry of the folded dipole, said first patch being provided with a slot with first and second edges defined on opposing sides of the slot, the second edge connecting halves of the folded dipole,a first dielectric substrate separating said first patch from said ground plane,supply means for said antenna,at least one second patch, said second patch being superimposed on said first patch and being substantially parallel to said ground plane, the second patch corresponding to the other half of the folded dipole,a second dielectric substrate separating said first and second patches,at least one first short-circuit connecting the second edge of said first patch with the second edge of said second patch.

Abstract
A planar printed-circuited antenna for the transmission and/or reception of microwave signals has a first conductive element or patch substantially parallel to a ground plane, a first dielectric substrate separating the first patch from the ground plane, supply structure for the antenna, and at least one second patch which substantially identical to the first patch. The second patch is superimposed on the first patch and is substantially parallel to the ground plane. A second dielectric substrate separates the first and second patches, and at least one first short-circuit connects the first and second patches to each other. According to the invention, at least one of the first and second patches includes at least one slot.
