The designed antenna can be performed 5G mm-Wave and V-band applications. The proposed microstrip patch antenna has a compact size rectangular shape structure of 5.02 mm  4.03 mm with a simple geometrical structure. Rogers RT 5880 (lossy) with a dielectric constant of 2.2 is used as substrate in this antenna with a thickness of .499 mm. The designed antenna covers multi-band operation. It resonates at 36.72 GHz, 41.73 GHz & 49.89 GHz mm-Wave bands with gains 6.615 dB, 6.017 dB & 5.752 dB respectively. The preferred antenna is designed with the benefits of low cost, compact size, good gain & efficiency by using microstrip feeding techniquesenThesis
