Abstract

This paper presents the design, realization and measurements of an Electronically Steerable Parasitic Array Radiator (ESPAR) antenna with enhanced performance of estimating the incoming signal direction. Designed antenna is dedicated for 2.4 GHz ISM applications with emphasis on Wireless Sensor Networks (WSN). Proposed antenna provides different radiation patterns by proper configuration of the parasitic elements. Thus, several ways of estimation of the incoming signal direction are possible. Apart from using the main directional beam, an additional method that uses minima of the antenna directional pattern is proposed.
