A novel ultra wideband stacked microstrip patch antenna (MPA) is proposed. In the new design the stacked patch is larger than the excited one. The thickness of the whole antenna is small as 5.5 mm. An impedance bandwidth (VSWR<2) of about 2.5:1 is achieved between 5.6 - 14.2 GHz when the excited patch and stacked one are co-centered at (0,0). The impedance bandwidth is improved to a ratio of 3:1 in the frequency range 5.6 -17.2 GHz when the stacked patch center is shifted to (3, 3 mm).
