Abstract :
This article presents beamforming algorithm of wideband smart antenna using Only Spatial Signal Processing in which its operation relies on the use of two-dimensional Inverse Discrete Fourier Transformer (IDFT) technique. The required weights at individual antenna elements are represented by real number which in practice can be realized by amplifiers or attenuators. Then we designed and constructed a full prototype of a smart antenna systems for wideband wireless communication in order to validate this algorithm. After that, the results of radiation pattern are compared between simulation and measurement.
