A bandwidth-enhanced Microstrip slotted array antenna is fabricated on an electrically-thin substrate to provide an economical solution for communication applications. To improve the impedance bandwidth of a rectangular micro strip patch without having any impact on its radiation characteristics, we perform etching of straight slot which is parallel and near to top side of the patch. For demonstrating the usefulness of the suggested technique, a planar array of dimension 6X6 with a side-lobe of 25 dB in both the E and H-planes are studied and fabricated on the FR4 substrate with 0.787 mm thickness. Simulation studies will be carried out on Method of Moments based EM Tool and analysis of the model is done by changing different operational parameters like the width of the slot, array element spacing, and array pattern. The antenna output parameters will be studied by changing substrate materials, εr ranging from 2 to 4.4 and complete analysis is presented in a detailed manner.
