Abstract

Mutual coupling is the one of the most important factor evaluating the performance of multiple input multiple output (MIMO) antennas. This paper presents the mutual coupling analysis by calculating total active reflection coefficient (TARC). PIFA is used for antenna arrays because of its low profile, good radiation characteristic, and robust of nearby antennas. We show that antenna spacing, antenna radiation pattern, and the number of antenna elements are more significantly considering factors in MIMO arrays. This paper demonstrates the optimized antenna elements allocation.
