In this letter, it is shown that the one fifth wavelength radiator combines with a printed ground-line which protrudes from ground-plane jointly with parasitic metal-loading, which can be used to control the near-fields of a mobile phone antenna. The human’s hand and head effect on impedance bandwidth and radiation characteristics of the proposed antenna is studied. The input power of 24dBm in CDMA, GSM and WCDMA bands, and the input power of 21dBm in DCS and PCS bands all meet the specific absorption rate (SAR) limit of 1.6mW/g and hearing aid compatibility (HAC) of M3 and M4 level.
