Abstract

A dielectric antenna is provided which is capable of setting the radiation of electromagnetic waves at a desired angle. The dielectric antenna has a nonradiative dielectric guide (an NRD
guide) of a construction in which a dielectric strip is sandwiched between a first planar conductor and a second planar conductor. A
dielectric resonator is disposed between the first planar conductor and the second planar conductor along the extension line of the dielectric strip, and a plurality of slots are disposed in the second planar conductor above the dielectric resonator and symmetrically with respect to the dielectric resonator.
