Claim 0:
1. A slot array antenna, comprising:
a dielectric layer having a first surface and a second surface opposite to the first surface;
a power feeding unit;
a first coplanar waveguide formed in a conductor layer provided on the first surface of the dielectric layer; and
a second coplanar waveguide formed in the conductor layer,
wherein each of the first coplanar waveguide and the second coplanar waveguide includes (a) a first end part connected to a point to which the power feeding unit is connected or situated in proximity and (b) at least one second end part connected to at least one slot formed in the conductor layer, wherein for each of the at least one slot formed in the conductor layer, a shortest distance from the slot to a nearest end edge of the conductor layer, which end edge is parallel to a longitudinal direction of the slot, is the same, wherein the power feeding unit is a strip conductor provided on the second surface of the dielectric layer, wherein the strip conductor is configured to feed power to the first and the second waveguides by contactless feeding, and wherein a portion of the strip conductor overlaps with the point when viewed in a direction perpendicular to the first surface and the second surface of the dielectric layer.
