Abstract

High data rate in wireless communication is a great demand in modern age, but the limited available bandwidth motivates the investigation and new area of research in wireless systems. Increasing demand for higher wireless system capacity has catalysed several transmission techniques, among which is the multiple-input/multiple-output (MIMO) technology has an attraction. In this paper, it has been compared among various multi-antennas (MA) at both the transmitter and receiver ends for significant capacity achievement. The use of antennas at both sides of the wireless communication link can result in high channel capacity provided the propagation medium is rich. Rayleigh fading has been considered as the propagation medium for verification. Also the performance has been measured in terms of bit error rate (BER) along with the capacity measurement. The result shows its performance. As the number of antennas to be increased for better performance, array structure is the suitable solution. The radiation pattern for linear array has been observed for maximum of 16 elements.
