Mutual coupling is a general phenomenon in many antenna arrays. Its existence causes many problems in the applications of antenna arrays and has attracted many researchers to study its causes and effects. The effect of mutual coupling on antenna arrays stretches over many different areas from the conventional use of antenna arrays to the modern employment of antenna arrays in such exotic areas as MIMO systems, diversity systems, biological imaging, sonar and radar systems. Over the past years, there have been many methods suggested to study the mutual coupling problem and many solutions have been suggested to tackle this problem. The development of ever-decreasing size electronic devices has favored the emergence of small-size antenna arrays in recent years. This places the studying of mutual coupling problem in an even more important priority.

This special issue will provide an international forum for researchers in antenna mutual coupling research to disseminate their results and ideas on this area.
