A novel surface treatment method of plating Cu+PPS film/coating on a mobile phone’s stainless steel frame for improving the antenna system efficiencies is proposed. The mobile phone was measured in free space, in a silicon cover, and in the hand and cover simultaneously. It’s found that with this surface treatment, the total efficiency of the antenna system can be improved in all the four cases respectively by 14.22%,1.38%, 15.19% and 1.72% at 940 MHz(GSM900:880–960 MHz), 2.59%, 3.21%, 4.81% and 1.43% at 1720 MHz(DCS:1710–1880 MHz) and 6.34%, 2.85%, 9.83% and2.32% at 2100 MHz(WCDMA:1920–2170 MHz). This lowcost surface treatment method is an important breakthrough to improve antenna system performance of mobile phones especially for those with a stainless steel frame, and suitable for mass production.
