Abstract
A novel leaky-wave antenna based on an image nonradiative dielectric guide with two dielectric slabs is designed, fabricated and measured. By selecting appropriate values of permittivities and thicknesses for the two slabs, the gain bandwidth can be enhanced to four times wider than the ordinary single-layer nonradiative dielectric antenna. With appropriate thickness of the dielectric slab, the beamwidth can also be adjusted.
