Abstract

A novel handset antenna consisting of two small antennas is proposed to mitigate finger loading effects. Both antennas are excited with a different phase in order to maximise the bandwidth. A phantom hand has been used to perform the experiments. It demonstrates how the finger affects the radiation behaviour for three particular positions of the finger over the antenna area. Experimental results feature a wider input impedance bandwidth and a higher degree of immunity to finger loading effects when compared with a single-element approach.
