This paper presents the results of simulations and measurements of an indoor localization system that uses Electronically Steerable Parasitic Array Radiator (ESPAR) antennas with switched directional beam. Proposed antennas are dedicated for 2.4GHz ISM low-cost applications where determination of the incoming signal is required. The antennas performance is analyzed and verified with relation to positioning methods based on the simplest direction of arrival (DoA) algorithm. The object position is estimated by incoming signal direction indicated by a pair of antennas. The existing analysis of ESPAR antenna performance with regard to DoA estimation methods usually base on experimental measurements where negative influence of the environment is limited or only certain operational angles are discussed. In this paper all measurements were done in the office and warehouse environment and compared with corresponding ray-tracing simulations.
