Abstract

A substrate integrated waveguide, SIW, antenna comprises a modified design of prior art SIW antennas that comprises an addition of electrically conducting means, e.g. vias, also along the substrate extending from the antenna aperture. By doing so, the SIW antenna of the present disclosure enables a reduction of mutual coupling between neighboring SIW antennas when arranged adjacent each other, e.g. in an array. Moreover, a reduction of back radiation in the SIW antenna can also be observed.
