This paper describes a new micro-strip patch antenna which is presented by using IE3D software. This antenna is named as \"A novel shield shaped micro-strip patch antenna\". Simulation results have been obtained which states that the micro-strip patch antenna possess predictable multi band characteristics. The results shows that the designed antenna can be operated in three different frequency bands with bandwidth of 3.06%, 2.19%, 2.57%. The resonating behavior in different frequency bands makes this antenna structure suitable for different types of applications with a directivity of 9.621dbi and antenna efficiency of 33.33%.
