A Comparative Study of Corrugated Ground Planes for GNSS Multipath Mitigation

Accuracy and precision of positioning, navigation, and timing using the Global Navigation Satellite System (GNSS) is important for current and future applications such as autonomous vehicles and Internet of Things. A major threat to the accuracy and precision of GNSS is multipath interference from reflections around the antenna. To combat this issue, reference station antennas use corrugated ground planes to suppress multipath signals. In this paper, a comparative study of performance, size, and weight of six corrugated ground plane solutions is presented.
