Abstract
This paper presents the analysis of a wideband circular polarized series-fed cross dipole antenna. By combining the vertical dipole antenna with the horizontal dipole with series feeding, a circular polarized wave can be radiated and the S11 bandwidth can be improved by forming an additional resonance. The measured peak gain, -10dB S11 bandwidth, 3-dB gain bandwidth and axial ratio is 4.12dBc, 0.87GHz(=41%), 2GHz(=68.9%) and 0.7GHz(=26.4%), respectively.
