Dielectri̇c lens antenna analysis with geometrical optics / physical optics approach

Adaptive cruise control, collision warning and mitigation, lane change assist, blind spot detection and object detection applications are becoming standards of automotive equipments. The higher performance and accuracy is needed for a safe driving experience. This is directly provided with the performance of the antenna used in the automotive application. Today, antennas with a 250 meters range and 30o angle are widely used in the radar applications. Planospherical lens antenna fed at focus spot with a microstrip antenna is one of the antenna types. In this thesis, a design of antenna system, which will improve safe driving technologies and will work beyond its opponents, is aimed with the consideration of future needs. Double lens antennas are studied at [1] thesis, Double lens antennas designed and advantages determined compared to planospherical lens antenna. Triple lens antennas are studied and designs could be used in automotive radar applications are recommended in this thesis project, which is a follow up project of [1] thesis. Convex, concave, planospherical and planoconcave lenses are used at design of the multiple dielectric lens antennas. GO/PO (Geometrical Optics / Physical Optics) methods, CST MWS (Computer Simulation Technology Microwave Studio) simulations and ray tracing algrothim are analyse methods used in antenna benchmark tests.
