| Since metamaterial concepts appeared, a new generation of slotted waveguide antennas has emerged. Current research into these antennas mainly focuses on analysis of simple prototypes, but synthesis still remains unexplored. This contribution deals with the design problem of a slotted antenna when the feeding waveguide shows a composite right/left-handed behavior. The use of the well-known design procedure by Elliott is proposed. A near-broadside six-slot array antenna, with a sidelobe level better than -18 dB, has been designed, constructed and measured. Good agreement is found between numerical and experimental results, confirming the validity of the synthesis approach suggested. | |
