A Band Reconfigurable Antenna for a Mobile Phone with the Metal Cover

摘要

This work proposes dual inverted-F antennas (IFAs) to obtain multi-band reconfigurable operation for a LTE/WWAN mobile phone with the metal cover. The impedance bandwidths across dual operating bands approach the bandwidth specification of the LTE / WWAN bands, respectively. The measured peak gains and antenna efficiencies are approximately 0.2 / 2.2 / 1.0 dBi and 36 / 55 / 66% across the LTE/WWAN bands, respectively.
