In this paper compact microstrip antenna with dual band circularly polarization has presented. Dual band for circular polarization is obtained using modified ground plane and by adding stubs to the feed line. The overall dimensions of the proposed antenna are 38mm×55mm×1.6mm.The antenna design is simulated using HFSS v.13 software which gives frequencies from 2.61-2.93 GHz (first band) and from 4.244.41 GHz (second band). Moreover, the proposed antenna provides reasonably good axial ratio bandwidth and return loss bandwidth for both the working bands. Proposed design is fabricated and measured.
