Abstract (en)

[origin: WO2017140987A1] This electromagnetically reflective plate (10) for a miniature antenna device includes: etched conductive elements (20, 22, 24, 26) on a first dielectric substrate layer (30); an apertured ground plane (32) placed between the first substrate layer (30) and a second dielectric substrate layer (38); a set of metal through-vias (42) formed in the thickness of the two substrate layers (30, 38), each having an upper end making contact with one of the conductive elements (20, 22, 24, 26), a lower end reaching a lower face (44) of the second substrate layer (38), and passing through the ground plane (32) without electrical contact in one of its apertures (40). Each conductive element (20, 22, 24, 26) makes contact with a plurality of vias (42) and each via of each conductive element is connectable to another via of a neighbouring conductive element using a corresponding electrical connection (46) making contact with the lower end of this via. At least some of the electrical connections (46) comprise one or more meanders.
