Riassunto analitico
This thesis presents the development and characterization of a dual-band GNSS antenna for automotive applications, designed to operate in the L1 (1575 MHz) and L5 (1176 MHz) bands. The main objective is to enhance antenna performance to support the precision and reliability requirements of advanced navigation systems, such as autonomous vehicles and intelligent driver assistance systems. Various design approaches are analyzed, including stacked patch antennas, slot antennas, ring antennas, and hybrid configurations, with an evaluation of performance metrics such as gain, axial ratio, bandwidth, and radiation pattern. A particular design was prototyped, measured in an anechoic chamber, and characterized in terms of dimensions and key performance parameters. Interesting results were obtained but further research is certainly needed to refine the design and address integration challenges.
