Abstract :
A novel integrated antennas are presented with dual frequencies and dual circular-polarizations (CP) in a common aperture. The proposed integrated antenna consisted of a crossed dipole antenna (CDA) and a modified quadrifidar helix antenna (MQHA). The CDA performs left-handed CP (LHCP) and covers 1.54-1.71 GHz with axial ratio (AR)<;3dB and VSWR <; 2. The MQHA performs right-hand CP (RHCP) and covers 2.15-2.52GHz & 2.7-3.43GHz with AR<;3dB and VSWR <; 2.
