abstract = "The omnidirectional circularly polarized (CP) antenna using a circular mushroom structure with curved branches is proposed. The antenna uses the zeroth-order resonance (ZOR) mode of epsilon negative (ENG) transmission line (TL) to obtain a vertical polarization and an omnidirectional radiation pattern. Also, the horizontal polarization is obtained by the curved branches. The measured 3 dB axial ratio is observed in 0-15° and 202-360° of an azimuthal plane.",
