The highly competitive environment of the automotive industry has made it one of the more productive sectors preoccupied in the realization of research and implementation of technological developments. Among them, there are navigation systems for vehicles, installed in at least one version of their models. These systems are formed by a global position system (GPS), with a pre-charged base of maps and highways in order to locate the vehicle. For the reception of the GPS signals, circularly polarized patch antennas are used, which must be designed to operate at 1.57 GHz. This work is focused on the analysis of a circular antenna performance, designed for GPS, by means of simulation, considering the following cases: antenna without radome, antenna with acrylic radome, and finally antenna on the roof of the automobile, considering the effect of the complete chassis. The simulation is carried out with the software FEKO.
