| Abstract: | Presents the novel design of the circular polarization (CP) for an annular-ring antenna operated at its TM11 and TM12 modes. Indication that the CP radiations of the proposed design are achieved by placing an L-shaped strip connected to two orthogonal sides of the inner boundary of the annular patch; Observation that broadside radiation patterns with good CP characteristics can be obtained at the two operating resonant modes. |
