Abstract: Microstrip antenna has many advantages. However, Narrow Bandwidth is the major disadvantage of this antenna in practical applications. This study proposes and investigates a dualband rectangular microstrip antenna with parasitic element fed by L-probe. The aim of the proposed research is to achieve dualband by electromagnetically coupling the two patches where one is driven and the other is parasitic. An L-shaped probe feeds the driven patch. The impedance bandwidth achieved is 63.35%, centered at 9.981 GHz and 33.48% centered at 13.99 GHz with a return loss >-10 dB. The antenna gain for the operating frequencies within the impedance bandwidth is 6 dBi.
