A CPW-Fed multiband planar antenna for mobile phone applications

This paper comes with a new study on the conception of a CPW-Fed multi bands planar antenna. The design takes into account that this structure can be integrated with circuits behind, that why the Fed is a CPW one. The antenna validated is suitable for GSM, DCS and ISM band. The entire area of the antenna is 36×72.5 mm2 and it is printed on an FR4 substrate. The printed U-shaped antenna is formed from two horizontal arms of different lengths and an L-shaped shorted strip which is connected between the vertical arm and the ground plane. The antenna is designed, optimized, and miniaturized by using ADS “Advanced Design System” and the results are compared with CST Microwave Studio.
