Wideband is the emerging technology for utilizing several wireless communication applications. So, for this the design of micro strip antenna along with parasitic element has presented in this paper. Normally, this micro strip patch antenna has a limitation of lower bandwidth. This limitation can be overcome by using technique called as parasitic element to achieve wider bandwidth. The antenna has been designed by using FR4 epoxy substrate that has the 4.4 dielectric constant and thickness taken as 1.6 mm. This designed antenna is composed of micro strip with parasitic elements and this has technique of micro strip feeding and the antenna return loss, gain and VSWR has simulated by the Hfss software. The return losses are -20.17dB, -17.28dB, -17.85dB, -19.82dB and the respective frequencies are 18.4Ghz, 23.3Ghz, 27.6Ghz, 33.7Ghz and this has the VSWR in between of 1 to 2. The designed antenna has a wideband of 30.05 GHz. The observed results are applicable in the k-band, ka-band & Q-band respectively.
