Abstract

This study proposes a small-size printed antenna with multi-band WWAN/LTE operation in a mobile phone by introducing dual parasitic shorted strips and a C-shaped ground plane. The obtained impedance bandwidths across LTE and WWAN operating bands approach 263 MHz and 1093 MHz, respectively. The proposed printed monopole antenna reduces the antenna size by at least 22 % since the overall antenna size is only 35 × 10 × 0.8 mm³. The measured peak gains and antenna efficiencies are approximately 2 / 3.6 dBi and 80 / 75 % for the LTE/WWAN bands, respectively.
