Abstract: The increasing importance of localizing objects in indoor environments is the motivation for many research on localization algorithms. This paper focuses on the design of a phased antenna array for the use in Angle of Arrival localization systems for indoor tracking. More precisely, a four element linear phased antenna array is developed based on the in-phase and quadrature demodulation and down conversion of the Radio Frequency signal (2.435 GHz) incident on each antenna array element. For this purpose the AD8437 demodulator is used. Steering of the array is performed on intermediate frequency (DC). The usage of available evaluation boards ts perfectly in the concept of willing to develop an architecture within restricted time. This in order to develop a proof of concept array to be used in future research dealing with the evaluation of Direction of Arrival estimation techniques. Following on an overview of the Angle of Arrival basics, this paper discusses the development as well as the need for calibration of the antenna array.
