Abstract
This paper proposes a printed cross dipole antenna with high gain and wide axial ratio bandwidth. The proposed antenna has a sequential-phase (SP) circularly polarized (CP) feeding loop, a 2x2 rectangular patch array which cut angle at the diagonal, and a metal reflector. This antenna achieves the gain-enhancing characteristic through the 2 x 2 patch array and metal reflection. The final measured 10dB impedance bandwidth is 64.32% (1.54-3.00GHz), the 3dB axial ratio (AR) bandwidth is 46.82% (1.68-2.71GHz), and the peak gain is 9.50dBi at 2.80GHz.
