This work is focused on the development of a prototype patch antenna designed for use as a replacement antenna in automotive Global Positioning Systems (GPS). In simulations and testing of the prototype, the focus was on the antenna gain. Transmission-reception testing was done to verify the operation frequency. The prototype was tested with a commercial GPS kit to evaluate its performance as a replacement antenna. Laboratory testing showed that it complied with the minimum requirements for both reception and transmission frequencies, while testing on a stationary vehicle showed slight variations when compared to the position data obtained using the same kit with its original antenna. In non-stationary testing, position determinations made with the prototype were sufficiently precise for use.
