A compact slotted patch antenna with the Defected Ground Structure (DGS) is proposed in this paper. The concept of DGS and slotted patch are integrated to get the multiple frequency bands, compact size, enhanced bandwidth, and gain. The antenna is designed on a low loss tangent substrate material Rogers RT/duroid 5870 with dielectric constant 2.2 and thickness 0.8 mm, dimensions of the patch are 14 mm X 20 mm, the antenna is excited by using the microstrip line feeding. The antenna is designed and simulated using ANSYS HFSS 18.0v at triple bands 2.5/4.9/7.0 GHz.Enhanced output characteristics are gain of 2.5/3.75/5dB, return loss -22/-35/-19dB, VSWR of 1.2/0.8/1.6dB and impedance bandwidth 300MHz/270MHz/690MHz at 2.5/4.9/7GHz.
