Design Of Novel Nine Shaped Multiband MIMO Antenna for Different Applications

Electronics and Communication Engineering

Multiple antenna systems are also well-known as Multi Input Multi Output (MIMO) systems which increases the capacity and reliability of any communication. The system with MIMO offers high quality of service and helps in achieving reduction in Bit Error Rate (BER) and it also have advantages like beam steering and diversity. MIMO purposefully signifies the practical technique for transmitting and receiving many data signals randomly through a single channel by multipath propagation. The microstrip antennas are widely used for communication systems due to their small size. Currently this antenna is commercially used for mobile communication and satellite communication and many other wireless applications. Micro strip MIMO is a complicated technology by using multiple antennas to overcome multipath fading propagation problem. Microstrip antenna is also known as patch antenna. In this project multiband novel nine shaped microstrip MIMO antenna is implemented. And the antenna design must produce satisfactory isolation and decoupling. The proposed antenna will operate at several frequencies. The major parameters associated with a MIMO antenna are Return loss (S11), Gain, Directivity, VSWR, Envelope Correlation Coefficient (ECC) and Diversity Gain (DG) and the implemented antenna should improve the gain, directivity and reflection coefficient and should be minimum.
