Abstract

PURPOSE:To increase the antenna gain and to give the redome function, by covering a specified dielectric radome on the upper face of a strip conductor, which is folded periodically and is formed on the surface of a dielectric provided with an earth conductor on the reverse face, to form an antenna. CONSTITUTION:A plane-plate earth conductor 12 is provided throughout the reverse face of a plane-plate dielectric substrate 11 of a proper thickness. A reinforcing metallic plate 13 is stuck to the conductor 12. A strip conductor 14 which is formed on the surface of the substrate 11 by selective etching and consists of copper or the like is folded periodically. A dielectric plane plate 15 of a thickness T is provided H above the earth conductor 12 in parallel with the face of the conductor 12 and is supported by metallic side plates 16 and 16. The thickness T of the plane plate 15 is set to about lambdaepsilon/4 (lambdaepsilon is the wavelength in the dielectric plate), and the specific inductive capacity is set to a large value. The height H on the conductor 12 is set to about lambdaO/2 (lambdaO is the free space wavelength). In this constitution, power is fed to one end S of the conductor 14, and the other Q is opened to form radiators A1-A13.
