Dualband L-Probe Fed Rectangular Microstrip Antenna with Parasitic Element

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.
