A novel reconfigurable quadratic antenna for wimax and 4G systems

A reconfigurable beam shaping of quadratic-aperture coupled antenna array is introduced. The 16 rectangular patches microstrip antenna is fed by an aperture coupled structure, which incorporates PIN diode switches that are integrated with the feed line. The activation of certain PIN diode switches c...
