A compact planar multi-broad band monopole antenna for mobile devices

摘要

A Multiple-frequency broadband planar monopole antenna is proposed in this Paper.The antenna is stimulated and numerically optimized by HFSS13.0(High Frequency Structure Simulator). The size of it is 39mm×22mm×1.7mm. The antenna resonates at many frequencies. The parameter S11≦-6dB means the proposed antenna matches well with its feed-line and covers many useful operation frequency bands, including 2G(DCS1800 and PCS1900), 3G(UMTS), 4G(LTE2300 and LTE2500), ISM, WLAN. It is quiet appropriate for the present ultra-thin smart phones.
