<p>The present invention provides a planer antenna which decreases in transmission loss, improves in aperture efficiency, increases in productivity, and reduces in cost when it is used in a high-frequency band such as submillimeter and millimeter wave bands, and which allows multibeam scanning and electronic-beam scanning with a thin, simple structure. According to one aspect of the present invention, the planar antenna includes a planar ground conductor, a plurality of radiating dielectrics arranged in parallel and at established intervals on a surface of the ground conductor, a plurality of perturbations for radiating an electromagnetic wave, the perturbations each having a given width and being arranged at established intervals on a top surface of each of the plurality of radiating dielectrics along a longitudinal direction thereof, and a feeding section provided alongside one end of each of the plurality of radiating dielectrics, for feeding an electromagnetic wave to a line constituted of each of the radiating dielectrics and the ground conductor. <IMAGE></p> |
