Abstract
A broadband antenna using a main and a sub antenna for the mobile communication terminal such as mobile phone and ITS terminal is designed. Two antennas are based on the hybrid antenna that is operating both a monopole and a IFA(Inverted F Antenna). It's applied the transmission line to connect both antennas. Sub antenna located in small space of the terminal allows space usability for the terminal design. Antenna for the hexa-frequency band of LTE700, CDMA, GSM, DCS, PCS and WCDMA is designed and implemented on the bare PC board that is same size of the mobile phone. This antenna was measured 3 : 1 VSWR over the whole design band. And average gains and efficiencies were-3.78 ~ -2.62dBi and 41.9 ~ 54.73% for LTE700/CDMA/GSM frequency band, -3.75 ~ -1.84dBi and 42.19 ~ 65.46% for DCS/PCS/WCDMA frequency band.
