Abstract :
In this paper, a shorted monopole antenna with coupled feed and parasitic strip for LTE/WWAN mobile handset applications is presented. A basic resonance of the shorted monopole along with the resonance formed by the coupled feed provides the enough bandwidth to cover the LTE700, GSM850, and GSM900 bands. By adding the parasitic strip, a matching characteristic of a harmonic of the monopole antenna and a loop resonance is improved to cover the GSM1800, GSM1900, UMTS, and LTE2300 bands. Consequently, the proposed antenna covers the LTE700, GSM850, GSM900, GSM1800, GSM1900, and UMTS bands. Stable and omni-directional radiation patterns are observed over the operating bands.
