Abstract

The purpose of this project is to analyze an Integrated Lens Antenna (ILA) for automotive radar application at 77 GHz. Lens Antenna is an attractive and competitive technology that gave a good performance and have low cost. It can be applied in the related fields like lane departure warning or pre-crash application. Different types of lens have difference dielectric constant that will give difference result in their distribution energy and surface wave. The objective of this project is to accommodate of analyzed a Lens Antenna with good distribution energy and reducing an excitation of surface wave. Beside that, the shape of the lens also will influence the result. A convenience method to eliminate substrate modes with integrated antennas is to place the antenna on a dielectric lens. The antennas placed on dielectric lens (homogenous dielectric feed) tend to radiate most of their power into the lens side. The shapes can be analyzed using Geometrical Optic (GO) Method and MathLab which is suitable.
