Abstract
The effect of the human body over the radiation of
handset antennas is a critical issue that have to be considered to
ensure a good handset antenna performance. Among the human
body effect, the finger is of particular interest since it is usually
placed over the antenna area which may cause detuning and/or
reduction of the efficiency. To mitigate the finger loading effects,
a novel handset antenna consisting of two small antennas
distributed along the ground plane is proposed. The distributed
antenna system is compared with a single antenna having a
broadband matching network, so both designs feature enough
bandwidth to cover the GSM850 (824-890MHz) and GSM900
(880-960MHz) communication systems. The finger effect is
analyzed in terms of efficiency using a phantom hand. Efficiency
is measured for different finger locations concluding that the
distributed antenna system is more robust to the finger loading
effect.Peer ReviewedPostprint (published version
