Hand phantoms for browsing stance in mobile phones

In this paper several antennas and configurations were investigated, focusing on phantom hands for browsing stance. It has been found that ldquooverlappedrdquo and ldquointerlacedrdquo grip styles have a similar impact on both absorption and mismatch loss, as only the fingers in close proximity to the antenna give a significant contribution in determining the total loss. Moreover, allowing different hands´ overlap configurations, it was found little difference in the loss amount. This suggests that a proper hand phantoms´ configuration may mimic the influence of many grip styles that despite being topologically different, influence the antenna efficiency in a similar way.
