Abstract
In this contribution a dielectric hemispherical antenna allowing wide range beam steering for 24 GHz radar applications is presented. A feeding concept for a hemispherical lens is developed using the geometrical-optical lens approach, therewith a high gain of 24 dBi is achieved with a lens radius of 90 mm. The lens is fed by a corrugated horn antenna to provide a low side lobe level up to a steering angle of 50°. 3D-electromagnetic field simulations and measurements confirm the antenna performance in the chosen scenario.
