Reduce the Hand-Effect Body Loss for LTE Mobile Antenna in CTIA Talking and Data Modes
The reduction in the radiation efficiency of an antenna in a mobile handset due to user's hand effects in the talking and data modes is studied. A parameter called "Body loss" is defined to evaluate the degradation of the radiation efficiency. A C-fed On-Ground (OG) PIFA antenna, which can cover two typical LTE bands of 0.75-0.96GHz and 1.7-2.1GHz, is used to study the property of the hand-effect body loss in two CITA test positions: the talking and data modes.
