1. A slot antenna comprising:
a substrate having a first side and a second side;
a first conductive layer on the first side of the substrate;
a second conductive layer on the second side of the substrate;
a first aperture in the first conductive layer;
a second aperture in the first conductive layer;
an aperture plate shaped to match the first and second apertures and defining an antenna aperture; and
