A compact stack antenna consisting of square loop resonators, aperture couples, feed line and the perturbation for dual- band and circular polarization (CP) applications is proposed in this paper. This perturbation applies both dual-mode and orthogonal mode efiects existing in the square loop resonator to present wide-band and CP characteristics simultaneously. The stack antenna presents the desired bands of 2.46GHz with bandwidth (BW) = 160MHz (6.58%) and 5.28GHz with BW = 450MHz (8.52%). The circular polarizations for dual-band are demonstrated with axial ratio (AR) spectrum and orthogonal modes. The proposed antenna is successfully simulated and measured with frequency responses, radiation patterns and current distributions.
