Analysis of Radiation Pattern and Beamforming in Phased Antenna Arrays for Indoor Localization and Scanning Systems

Abstract

This paper presents an analysis of radiation pattern and beamforming in phased antenna arrays for indoor localization and scanning based on a triangulation technique. Beamforming is obtained and steered by applying a linear phase shift between antenna array elements, which provides a simple and power efficient design. Various antenna array configurations are studied by numerical simulation means in order to obtain an optimal beamforming necessary for indoor localization and scanning systems in wireless sensor network.
