摘要： In this letter, a new single-anchor indoor localization concept employing electronically steerable parasitic array radiator (ESPAR) antenna has been proposed. The new concept uses a simple ?ngerprinting algorithm adopted to work with directional main beam and narrow minimum radiation patterns of ESPAR antenna that scans 360 area around the base station, while the signal strength received from a mobile terminal is being recorded for each con?guration. The letter describes the antenna design and necessary ?ngerprinting algorithm expansion and shows measurements of the proof-of-concept prototype performed within the experimental setup. Localization results obtained from indoor measurements indicate that the proposed concept can provide better results than the similar approach based on a switched-beam antenna introduced by Giorgetti et al. (IEEE Commun. Lett., vol. 13, no. 1, pp. 58–60, Jan. 2009).

[Institution of Engineering and Technology 12th European Conference on Antennas and Propagation (EuCAP 2018) - London, UK (9-13 April 2018)] 12th European Conference on Antennas and Propagation (EuCAP 2018) - RSS-Based Direction-of-Arrival Estimation with Increased Accuracy for Arbitrary Elevation Angles Using ESPAR Antennas
摘要： In this paper, we have proposed an improved direction-of-arrival (DoA) estimation algorithm, which uses the power pattern cross-correlation (PPCC) estimator and received signal strength (RSS) values recorded at electronically steerable parasitic array radiator (ESPAR) antenna’s output port, providing more accurate DoA results for unknown signals impinging the antenna. The PPCC estimator in its original form provides accurate DoA estimation results for directions lying within the horizontal plane. However, the estimation accuracy drops for other elevation angles as the estimator relies on ESPAR antenna’s radiation patterns measurements in the horizontal plane only. Our proposed modification allows one to measure ESPAR antenna’s radiation patterns in two different elevation planes during the calibration phase, which improves PPCC-based DoA estimation algorithm’s overall accuracy for signals impinging the antenna from arbitrary elevation angles. The proposed algorithm has been verified during anechoic chamber measurements using our ESPAR antenna prototype.
