Planar printed shorted monopole antenna with coupled feed and stub for LTE/WWAN mobile handset applications

In this paper, a shorted monopole antenna for LTE/WWAN mobile handset applications is presented. The antenna consists of a monopole, a coupling strip, a feeding pad, a stub, and a shorting strip. The basic resonance of the monopole combines with the resonance formed by the coupling that occurs between the coupling strip and the feeding pad to include the LTE700, GSM850, and GSM900 bands. The resonance of the stub combines with the harmonics of the monopole to include the GSM1800, GSM1900, and UMTS bands. Therefore, the proposed antenna covers the LTE700, GSM850, GSM900, GSM1800, GSM1900, and UMTS bands.
