Multi-band Folded Monopole Internal Antenna for Mobile Handset Applications
Abstract
In this paper, a multi-band folded planar monopole internal antenna for mobile handset applications is proposed. The proposed antenna has multi-resonances, which is different from a conventional folded monopole antenna, and it provides a wide bandwidth at high frequency bands. The measured impedance bandwidth (VSWR < 3) is 180 MHz and 1880 MHz in lower and higher frequency bands, respectively. The proposed antenna can effectively cover most wireless communication bands including CDMA, GSM, GPS, DCS, PCS, and W-CDMA, WiBro and S-DMB.
