Abstract :
This paper reports a study of specific absorption rate (SAR) for LTE MIMO antennas in mobile phones, with special consideration to the effects of different chassis lengths and different types of MIMO antennas. Two designs of dual elements MIMO antenna are studied under two typical LTE and mobile phone frequency points. The simulations are carried out both for a specific anthropomorphic mannequin (SAM) head phantom and a flat phantom. The measurements on the flat phantom are carried out as well to verify our simulation results.
