PURPOSE: A radio wave lens and a manufacturing method thereof are provided to change easily an operational frequency band by performing an operation as a hyper lens in a microwave band. CONSTITUTION: A plurality of flexible dielectric substrates(110) having metal patterns are bent in a shape of a semicylinder, respectively. The flexible dielectric substrates are laminated in a radial direction to have a concentric axis. A gap between metal patterns(120) and a gap between dielectric substrates are set in small in comparison with a wavelength of an incident wave. Dielectric substrates(130) are separated and laminated from each other. A space between the dielectric substrates is filled with air or an additional dielectric. |
