| A monopole antenna with parasitic structures enabling multiband operation for WWAN/LTE mobile terminals is proposed. The antenna is comprised of one folded monopole strip, two parasitic shorted strips and a matching network. The overall antenna dimension is only 38.3 mm* 11.4 mm*0.8 mm, which is appropriate for mobile phone applications. The measured impedance bandwidths (S11<-6 dB) are 340MHz at the low band (0.82-1.16GHz, 34.3% FBW) and 1.39 GHz at the high band (1.61-3GHz, 60.3% FBW). Within the frequency band of interest, good radiation performances are obtained. The proposed antenna is applicative for WWAN/LTE mobile terminals including mobile phones, data cards and wearable devices. |
