Design of a Meander-Shaped MIMO Antenna Using IWO Algorithm for Wireless ApplicationsAbstract
Using a MIMO antenna system is a well-known technique to enhance the performance of wireless communication systems. In order to create a MIMO antenna system on a wireless device, two or more antenna elements could be placed in a very small space. Thus, the mutual coupling including radiation pattern coupling between closely arrayed antenna elements causes the decrease of a MIMO antenna performance. It means that we must consider not only the antenna size but also the suitable antenna array method to design the MIMO antenna system. The aim of this research was to design an antenna for a fourchannel multiple input multiple output (MIMO) system that works at 5.8 GHz with consideration of the mutual coupling. The geometry of the antenna is optimized by using Invasive Weed Optimization algorithm to accomplish high degree of isolation. The measurement and simulation results of reflection coefficient, mutual coupling and radiation pattern are presented and discussed.
