This paper describes a coaxial probe-fed slotted antenna with Defected Ground Structures (DGS) which can be tuned to resonate at our desired frequency bands by changing the position of DGS and width of the slots in the ground plane. The proposed antenna can be made to work in the WLAN (2.4/5.2/5.8 GHz) band and WiMAX applications. In this paper, we have tried to reflect a detailed study of the slots in the ground plane and its effect on the antenna parameters such as gain, polarization, return loss, radiation pattern, etc. The proposed antenna produced a multi-band application providing return loss of 11.81 dB at 1.69 GHz, 18.81 dB at 2.5 GHz, 19.59 dB at 2.89 GHz, 22.98 dB at 4.81 GHz, 19.80 dB at 5.80 GHz and 12.70 dB at 6.17 GHz by using FR-4 Epoxy substrate with dielectric constant (Ɛr) of 4.4 and a substrate height (h) of 1.60 mm.
