Abstract :
The influence of the user´s body degrades small antenna performances. This paper investigates the detuning and the losses on high-Q planar antennas for small devices due to user proximity. The results at low frequencies for the Long Term Evolution (LTE) standard are compared to the results for a low- Q antenna. Two hand grips are studied and combined to a SAM(Specific Anthropomorphic Mannequin)phantom. It is shown that using the high-Q antennas the loss due to the mismatch is reduced but the absorption loss is increased.
