In this paper results on Triple-band Antenna array designed to operate at a Resonance frequency of 4.7 GHz, 6.7 GHz and 8.1 GHz has shown. Circularly polarized square slot antenna (CPSSA) has been used as single Antenna. Each single Antenna consists of inverted L shape grounded strips located at slots opposite corner to reduce cross polarization. The antenna is fed by symmetric coplanar waveguide. In this paper CPSSA performance has been increased in terms of impedance bandwidth and axial ratio bandwidth by using sequential rotated feed. Here sequential rotated feed technique is constructed by using 2×2 antenna array. This technique provide extra large enhance impedance bandwidth of 4.5 GHz in the range of 4.5 GHz to 9 GHz and it also enhance 3dB axial ratio bandwidth for VSWR 1.23.
