A substrate integrated waveguide to air filled waveguide transition includes an electrically conductive top layer, an electrically conductive base layer spaced apart from the top layer, wherein the top and base layers each extend along a length axis from a first end to a second end of the transition, the top layer defining a width axis normal to the length axis in the plane of the top layer, and wherein a separation between the top layer and base layer increases towards the second end in a transition region, wherein the transition further includes a dielectric layer sandwiched between the top and base layers, the dielectric layer including a taper portion having a width which tapers to a point at an end point between first and second ends, the width of the taper decreasing towards the second end. |
