Design and Performance Analysis of MIMO-DSSS System for 2.4 GHz ISM Band Wi-Fi Applications Using Microstrip Antennas
In this paper, compact antenna has been designed and implemented in a 2X2 Multiple-Input Multiple-Output (MIMO) system. 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. Polarization diversity of the two antennas is used to construct independent and uncorrelated signals on each antenna. The antennas are designed on CST microwave studio simulation software with return loss less than -10dB, and the two antennas are combined as a single system forming a MIMO array of two antennas.
