摘要：
A high gain, circularly polarized 4x4 antenna array, is proposed. A circularly polarized magneto-electric (ME) dipole element is used as a radiating element. The 4x4 antenna array excited by slots and feeding networks of microstrip ridge gap waveguide (MRGW). A compact design is archived with including the effect of the mutual coupling. The simulated 4x4 array achieved an impedance bandwidth of 20.8% for vertical bar S11 vertical bar < -10 dB with a maximum gain of 20.3 dBi, which is higher than any reported 4x4 array antenna. An axial ratio bandwidth of 18.3% is achieved.
