Abstract (en)
[origin: WO2020187983A1] Apparatus (100) comprising - a dielectric substrate (101; 152) having a top plane and an opposite bottom plane with an at least partial metallization (153), - a ridged waveguide (200), - a metal patch (104), integrated in said dielectric substrate (101; 152), which comprises at least one conductive via hole (108) connecting said metal patch (104) and said metallization (153), - a slot (103) being provided in said metal patch (104) and having an orientation with respect to a first axis (x) of said top plane being defined by an angle in the range 0° < angle < 360°, wherein said ridged waveguide (200) - is field-coupled to said slot (103) via an air gap, which extends parallel to said top plane, so as to be able to couple an electromagnetic wave travelling along said ridged waveguide (200) via said air gap into said slot (103) and/or to couple an electromagnetic wave emitted by said slot (103) via said air gap into said ridged waveguide (200).
