Fig. 2

Example of geometric configuration for the phase-based localization of a passive tag (f = 868 MHz, λ = 35 cm): two readers are considered in coordinates [−1, 0] (blue) and [1, 0] (red); a tag is considered in [0, 2] (green). Intersections of circles denote the possible locations of the tag considering the two phase measurements (first 20 displayed)
