Abstract
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 (3) is sandwiched between a first planar conductor (1) and a second planar conductor (2). A dielectric resonator (4) is disposed between the first planar conductor (1) and the second planar conductor (2) along the extension line of the dielectric strip (3), and a plurality of slots (2a, 2b) are disposed in the second planar conductor (2) above the dielectric resonator (4) and symmetrically with respect to the dielectric resonator (4).
