Compact Modified Printed Monopole Antenna for Enhanced Gain Performance

A novel Coplanar Waveguide (CPW) fed modified printed monopole antenna with enhanced gain is presented in this paper. The antenna has a maximum gain of 6.88dBi with a 2:1 VSWR band width of 45 % from 1.99GHz to 3.03GHz. High gain performance is achieved by folding the ground plane of a CPW fed printed monopole perpendicular to the plane of the monopole main arm. The antenna exhibits good radiation and impedance matching characteristics as that of a CPW fed ordinary printed monopole. The antenna has a dimension of 17 X 42 X 6.4 mm and highly suitable for slim mobile handsets.
