a, Illustration of the steps to position the reader antenna. b, Contour plot of the received harmonic signal power when the position of the antenna is scanned within a 40 mm × 40 mm area. c, Measured backscattering signal for the antenna positions in (b). Yellow shading indicates the 10 mm × 10 mm area with highest signal amplitude. d, Resonant frequency and received power as a function of the orientation angle of the antenna. Blue shading denotes the frequency uncertainty due to decrease in the signal-to-noise ratio. e, Harmonic backscattering spectra for varying orientation angles.
