Summary:
In authors’ previous studies, a printed rectangular monopole antenna for circular polarization has been proposed. The radiation characteristics of the wideband circular polarization are achieved by designing the antenna asymmetrically to microstrip line. The simulated bandwidth of 3dB-axial ratio with 10dB-return loss is approximately 56%. In this paper, a printed elliptical monopole antenna is proposed to enhance the bandwidth further. The bandwidth of the proposed antenna is approximately 84%. The gain at highelevation angle is stable within the frequency range compared with the rectangular monopole antenna.
