Claim 0:
1. An antenna system, comprising:
a first substrate;
a slot array defined by a conductive layer disposed on the first substrate with a coplanar waveguide joining a number of side slots arranged in a line forming the slot array;
a second substrate spaced apart from the first substrate;
a ground plane defined on the second substrate; and
a defined volume waveguide disposed between the first substrate and the second substrate,
wherein the coplanar waveguide extends along the first substrate parallel to the defined volume waveguide with the slot array and the defined volume waveguide each substantially filling areas around the first substrate that are substantially common in size,
wherein the system is configured to radiate a radiation pattern in a hybrid mode from a combination of both the slot array and the defined volume waveguide.
