Abstract :
A single-feed CP-GAA with an open stub is proposed. It is found that the open stub is suitable for impedance matching. The open stub does not distract the radiation characteristics. This CP-GAA has an approximately 2% frequency bandwidth for a 3-dB axial ratio criterion. Across this 3 dB axial ratio bandwidth the VSWR is less than 2, and the gain is approximately 14 dBi.
