Abstract: This paper introduces a circularly polarized ulta-wideband monopole antenna. The antenna is designed by etching two asymmetrical cuts on both sides of the conventional rectangular radiator with opposite orientation. This modification resulted ulta-wideband and circular polarization nature in the patch. The obtained impedance bandwidth and axial ratio bandwidth are 7.6 GHz (3-10.6 GHz) and 1.1 GHz (7.7-8.8 GHz). Prototype of the suggested patch having dimensions 35mm × 31mm × 1.6mm is simulated. Subsequently the patch is fabricated, experimented and compared with simulated results. The antenna can be applicable to wireless personal area network, secure military communications, microwave imaging etc.
