Claim:
1. A radiating structure comprising: a waveguide layer configured to propagate electromagnetic energy via a waveguide in the waveguide layer, wherein the waveguide has a height dimension and a width dimension; a radiating layer coupled to the waveguide layer, wherein: the radiating layer is parallel to the height dimension of the waveguide; the radiating layer comprises a plurality of radiating slots along the length of the radiating layer, wherein each radiating slot: is defined by an angular or curved path, is coupled to the waveguide layer, has a rotational orientation relative to a dimension of the waveguide and to the other slots, wherein the rotational orientation provides a desired coupling factor, and has a same effective length greater than the height dimension of the waveguide, wherein the effective length is measured as the entire path length along the angular or curved path of the slot.
