User Effect on Antenna Cluster Based MIMO Antenna
User Effect on Antenna Cluster Based MIMO Antenna
This paper studies the benefits of the antenna cluster technique in exciting the orthogonal modes of a metal rim for MIMO operation in the low-band frequencies. The user effect with antenna clusters is studied with measurements of antenna prototype held by a hand phantom. On average, better than 20% total efficiency is achieved over the low-band frequencies and almost 30% average efficiency over the higher frequencies which suggests that the antenna cluster technique can be used to design user effective mobile device antennas.
