Patent ID: 7091907

Claim:
A printed antenna comprising two substantially stacked radiating elements ( 25 , 45 ) of planar form, a first reactive coupling layout ( 5 , 15 ) able to excite one of the radiating elements ( 25 , 45 ), this first reactive coupling layout comprising at least one feed line ( 6 , 7 ) and one conductive ground plane ( 15 ) furnished with at least one coupling slot ( 16 , 17 ), the antenna furthermore comprising a second reactive coupling layout ( 25 , 35 ) able to excite the other of the radiating elements, characterized in that the two radiating elements ( 25 , 45 ) have surface areas whose values are sufficiently similar for exhibiting a relative discrepancy of their surface areas which is less than 20% so that the first reactive coupling layout produces a simultaneous coupling of the two radiating elements ( 25 , 45 ), wherein at least one of the two radiating elements ( 25 , 45 ) is etched on a layer comprising a uniplanar ground plane, said radiating element isolated from said ground plane by a slot hugging its contour.
