Abstract

This paper presents an analysis of beamforming and radiation pattern of various phased antenna arrays configurations which are intended for use in low cost Radio Frequency Identification or Wireless Sensor Networks applications for wireless process monitoring and location. The location process is based on the estimation of direction-of-arrival by determining the angle-of-arrival of radio signals. The beamforming and the steering of the antenna’s lobes are obtained via a linear phase excitation of the signal applied to the array elements. Several configurations of various geometries and sizes are analyzed in order to obtain an array with narrow main beam and good scanning capabilities. Finally, the main elements of the developed hardware implementation involving phase shifter based on vector modulators are discussed. Ill. 14, bibl. 14 (in English; abstracts in English and Lithuanian).
