Abstract
A 2×2 circularly polarized magnetic-electric dipole array which adopts sequential-rotated feeding technique to broaden the bandwidth with the total size of 1.68λ0 × 1.68λ0 × 0.08λ0 is presented in this paper. The antenna element utilizes an obtuse-triangular structure to reduce the antenna profile to only 0.08λ0. The simulated results show that an impedance bandwidth of 21.4% (VSWR<1.5) from 1.88GHz to 2.33GHz is achieved, which is overlapped by the 3dB axial ratio bandwidth of more than 28.6% from 1.8GHz to 2.4GHz. A stable gain of 11.6 ± 1.2dB is realized in this operation frequency bandwidth.
