Abstract

New techniques are being devised to use RFID technology to enable Indoor Position tracking of tagged objects. RFID holds immense promise in this area as tags are cheaply available and robust to various kinds of RF interference. In this paper, passive UHF (868MHz) tags placed at uniformly spaced points in a grid in different sets of orientations are used to find out the contour patterns of reader antenna in a given area under static environment. This information is used to estimate the position of unknown tags from the readings obtained by the reader antennas. The computed results are presented and discussed.
