In, this paper, compact antenna have been designed and implemented in a SISO system and multiple antenna systems including 1X2 SIMO, 2X1 MISO and 2X2 MIMO systems respectively. The antennas are compact double-sided printed microstrip patch antennas and fed by a microstrip line designed for a frequency of 2. 4 GHz used for industrial, scientific and medical (ISM) band applications. The antennas are designed on CST Microwave studio simulation software with return loss less than -10dB, the MIMO system is designed using polarization diversity of the individual antennas which yields better result in terms of return loss (S11 and S22) and mutual coupling (S12 and S21). Furthermore, a capacity analysis of the above systems is done on MATLAB software. Multiple-Input Multiple-Output (MIMO) systems offer highest capacity to wireless systems compared to the others. The system is designed for an operation frequency of 2. 4 GHz with MIMO system that offers an increased data rate.
