) communication: Aim to increase the radiation efficiency
MI MIMO
Aim to increase MI channel capacity
Spread Resonant Strategy (RS)
---> Instead of using the same resonant frequency for all the MI coils, the spread resonance strategy allocates different resonant frequencies for different MI relay and transceiver coils.
Best operating frequency
---> Related to the distance between MI coils
Parasitics capacitance
---> Depends on the frequency

Drawbacks
Low radiation efficiency
--->The metamaterial-enhanced magnetic induction has been developed to increase the signal strength
Extremely narrow bandwidth
--->MIMO antenna array is proposed to increase MI bandwidth
Dramatic polarization loss
--->the tri-directional coil antenna is used to overcome the polarization loss.
