Compact MIMO antenna arrays using metamaterial hybridization band gaps

In this talk, we show how the concept of hybridization band gap in metamaterials can be utilized to create antennas for MIMO applications. Those strongly decoupled antennas present at the same time a very small form factor and a very low correlation. To that aim, we first explain briefly the concept of hybridization between a resonator and the free space waves continuum. Then we expose the methodology we use to design multi-ports antennas based on that concept. We present results of several antennas designed using this idea, especially in the wifi bands, and give potential solutions for multi-band compact MIMO antennas for LTE applications.
