Hand + head effect on mobile terminal antenna Measured absorption & mismatch losses in the calling mode with different hand grips.• Results show that the user’s hand very close to the antenna element causes a large influence on the antenna operation.• Total efficiency decrease is mainly due to the absorption to head and hand.• The user caused impedance mismatch has a minor influence on the total efficiency decrease.M.
