Abstract
This paper investigates the effect of antenna directivity on the accuracy of fingerprint-based indoor localisation systems. The proposed method adopts received signal strength which was derived by ray tracing techniques applied to 3D indoor model for location determination. Antennas with different radiation patterns and different orientations are implemented for comparative study. Numerical results show that, by utilizing the geometry of the indoor environment, directional antennas can help increase the uniqueness of the fingerprints and hence improve the localisation accuracy.
