Internet of Things (IOT) and Radio Frequency Identification (RFID) are famous technologies which will help widely for the civilian and military applications, visually impaired people to solve their daily life problems, identifying and tracking a tag attached to an object etc. In this paper, a Microstrip patch Antenna with a high Gain along with a good Return Loss (S11) and VSWR that will work for 5.8 GHz ISM band RFID applications, is proposed. The Antenna has been designed and simulated using dielectric substrate FR4 glass epoxy having dielectric constant 4.4. The Patch dimensions are 96 X 156.5 X 1.6 mm3 and has a Microstrip Line feed. The microstrip patch antenna with DGS has return loss of -15dB and the VSWR is 1.43 at 5.8 GHz frequency. The Gain is also improved about 5.81 dB. As compared to the UHF band designs, the proposed design provides a better range coverage as well as better speed since the Gain is high. The designed antenna has a rectangular shape Defective Ground Structure and is designed with the help of Ansoft High Frequency Simulation Software (HFSS).
