A compact multiband planar monopole antenna for WWAN/LTE applications is proposed. The proposed antenna consists of a folded monopole with a resistance load and a shorted parasitic strip. The antenna is printed on the FR4 dielectric substrate and the dimension of the antenna is only 43mm×10mm×0.8mm. The antenna prototype has been fabricated and measured to verify the performance of antenna. The measured results agree with the simulated results well. In the case of VSWR smaller than 3:1, the proposed antenna is capable of covering GSM850, GSM900, DCS, PCS, UMTS 2100, LTE2300 and LTE2500 bands. The proposed antenna is suitable for WWAN/LTE mobile devices. |
