Body-loss for popular thin smart phones

In this contribution, an investigation of the radio performance of recent popular phones has been done. The antenna performance has been evaluated with the newly agreed phantom head-hand measurements of the mobile antenna efficiency. It has been observed that the newer generation thin smart phones have worse performance than the classical phones and more surprisingly there is a loss in performance between generation of the same brand of smart phone. The effect of the performance variation between phones has been illustrated by calculating the coverage area for the voice service for Denmark with data from all mobile operators for the best and worst performing ones.
