An antenna is a structure i.e., generally of metallic objects, wire, or group of wires used to convert high frequency current into EM wave and vice versa. Like an antenna is used in transmitter side then it converts high frequency current into EM wave and if it is used in receiver side then it will catch the EM wave and convert it into electrical signals. This paper focuses on present day scenario of communication through MIMO technology. MIMO systems are high in demand because of their versatility features. They offer high data rates, throughput, different frequency of operability as per demand and many more. Because of this it finds application in LTE, WiMax, HSPA+ and other wireless communication and latest technologies.
