Abstract :
A new global positioning system (GPS) antenna design based on the reduced-surface-wave (RSW) microstrip antenna concept is introduced. In addition to retaining the advantages common to microstrip antennas, these new GPS antennas will be shown to provide comparable performance to the most commonly used GPS antennas, including choke-ring designs. The reduced horizon and backside levels, and good circular polarization characteristics indicate that this new antenna design is ideal for high-precision GPS applications.
