A navel circularly polarized (CP) textile patch antenna is presented in this paper. To our knowledge, it is the first textile antenna with circular polarization and for the first time, we show that more sophisticated design methods are also applicable to flexible textile antennas. The antenna uses a single inset microstrip feed-line. To achieve proper CP operation, truncated carners along with a single slit in patch are applied. The 3-dB axial-ratio CP bandwidth is about 3%, which represents a very good result even compared to standard, hard substrate CP antennas.
