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 a 8-elements linear array with a finite reflecting plane and its adaptive behaviour 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 (PSO) 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.
