| Abstract: | A S band and a C band circularly polariged stacked antenna is designed respectively using the experimental formalas combined with the HFSS simulation tools.The resulting impedance bandwidths of the designed antennas achive 18.2% and over.The characteristics of the circularly polarigation of stacked antenna are researched working at different frequency band.Some steps are proposed to improve the deteriorated axial ratio and the asymmetric beam pattern of the C band stacked antenna. |
