In this letter, the structure of the prototype of a smart antenna working in the 2.4-GHz band is described. The radiating structure is composed by an eight-element linear array with a finite reflecting plane and its adaptive behavior is obtained by means of a set of electronically driven vector modulators that control the array weights. The antenna system is equipped with a control software based on a particle swarm optimizer algorithm that enables the system to adapt to the complex interference scenario. A selected set of numerical and experimental results are reported and discussed to assess the effectiveness of the proposed architecture.

Abstract
In this letter, the structure of the prototype of a smart antenna working in the 2.4-GHz band is described. The radiating structure is composed by an eight-element linear array with a finite reflecting plane and its adaptive behavior is obtained by means of a set of electronically driven vector modulators that control the array weights. The antenna system is equipped with a control software based on a particle swarm optimizer algorithm that enables the system to adapt to the complex interference scenario. A selected set of numerical and experimental results are reported and discussed to assess the effectiveness of the proposed architecture.| File | Dimensione | Formato | |
