Abstract :
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 wireless handy device, two or more antenna elements could be placed in very small space. Thus, in case of a MIMO antenna in mobile handy terminal, 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 for mobile handy terminal. In this research, a 2-channel MIMO WiBro antenna and 1-channel PCS band antenna are designed with consideration of the mutual coupling.
