By connecting small ring strip in the original Wilkinson power divider, |S11| bandwidth increases from 23.52% to 35.61% with improved impedance matching from −14.16 to −35 dB. In case of axial ratio, the small ring strip improves the 3-dB axial ratio bandwidth from 14.92% to 15.21%. The proposed antenna provides measured |S11| and 3-dB axial ratio bandwidth of 40% and 9.24%, respectively. The left-handed circularly polarized is greater than right-handed circularly polarized by 10 dB in both xz and yz planes and the measured peak gain is 10.1 dB. © 2017 Wiley Periodicals, Inc.
