Head and hand detuning effect study of narrow-band against wide-band mobile phone antennas

Abstract

Wide-band (WB) and narrow-band (NB) antennas in terms of performance are compared, when interacting with the user's right head and hand (RHH). The investigations are done through experimental measurements, using standardised head phantom and hand. It is shown that WB antennas detune more than NB antennas, but the drop in efficiency, when placed in RHH position, is similar for both antennas. © 2014 The Institution of Engineering and Technology.
