A planar leaky-wave antenna offering beam steering at broadside using surface-wave launchers

New developments of a novel 2-D LWA with maximum gain at broadside have been presented. By the design of an array of SWLs the SW field distribution on the substrate can be controlled and thus broadside beam steering can be observed at a single frequency. Such SWLs can also be used in the design of novel planar circuit structures for guided and radiated applications at millimeter-wave frequencies.
