1. A slot antenna comprising:
a substrate integrated waveguide (SIW) comprising a plurality of slots;
wherein each of the plurality of slots comprises:
a first elongated opening elongated along a length direction of the slot antenna;
a second elongated opening elongated along the length direction to be parallel to the first elongated opening; and
a connecting opening connecting the first and second elongated openings,
wherein a first center axis of the first elongated opening is offset from a second center axis of the second elongated opening, and
wherein the connecting opening is obliquely angled with respect to the length direction such that the first and second elongated openings do not overlap in a direction orthogonal to the length direction.
