A compact slotted micro strip patch antenna is proposed and designed in this paper for millimeter wave Radar applications. The antenna is designed on Quartz glass substrate of dielectric constant 3.78 with thickness of 0.8mm. The size of the proposed antenna is 4mm x 9mm x 0.8mm. The proposed antenna resonates at three frequencies 24.42 GHz (24.17-24.69), 27.02 GHz (26.74 ? 27.32) and 34.67 GHz (33.89 ? 35.47). A comparative analysis is done by varying the dimensions of the slots in antenna. The proposed model is simulated using Finite Element Method based High Frequency Structure Simulator (HFSS).
