Avoiding the interaction between hand and capacitive coupling element based mobile terminal antenna

Avoiding the interaction between hand and capacitive coupling element based mobile terminal antenna

Interaction between a mobile terminal antenna and a hand of a user is investigated with an experimental study using capacitive coupling element antennas and homogeneous anthropomorphically shaped hand phantoms. The frequency bands used in the study are 880-960 MHz and 1710-1880 MHz. The significance...

description Interaction between a mobile terminal antenna and a hand of a user is investigated with an experimental study using capacitive coupling element antennas and homogeneous anthropomorphically shaped hand phantoms. The frequency bands used in the study are 880-960 MHz and 1710-1880 MHz. The significance of the shape, size and position of the antenna element on the antenna input impedance and efficiency in the presence of a hand phantom is demonstrated. The results indicate that a part of the hand-originated losses can be avoided by taking the hand effects into consideration in antenna design.
