Abstract
An antenna system operates in a hybrid coplanar waveguide and rectangular waveguide mode. A slot array with a conductive layer is disposed on a substrate and defines a coplanar waveguide joining a number of side slots arranged in a line forming the slot array. Another substrate is spaced apart from the substrate and a ground plane is defined thereon. A defined volume waveguide is disposed between the substrates. The array is configured to radiate a radiation pattern in a hybrid mode that results from a combination of the slot array and the defined volume waveguide. The side slots may be elliptical in shape for side lobe level reduction.
