Abstract

By introducing a modified F-shaped feeding strip and dual parasitic shorted strips, a small-size wireless wide area network/long-term evolution (WWAN/LTE) printed antenna is proposed and embedded in the 4 G mobile phone with octa-band operation. The operating impedance bandwidths (RL ≥ 6 dB) of 263/1093 MHz can be obtained across the LTE/WWAN bands, respectively. The overall antenna size of the proposed printed monopole antenna (MA) is only 35 × 10 × 0.8 mm3. Meanwhile, this small-size MA provides the measured peak gains and antenna efficiencies of 2.0/3.6 dBi and 80/75% for the LTE/WWAN bands, respectively.
