Abstract

In this paper, we propose a new circularly polarized circular magneto-electric dipole antenna. The proposed antenna has a wide impedance bandwidth of 66.66% from 3.0 to 5.4 GHz, high stable gain with maximum gain of 9.3 dBi at 4.0 GHz and wide 3-dB axial ratio bandwidth of 44% from 3.5 to 5.35 GHz. The radiating element is smaller in size by 35% while maintaining a high stable gain, and wide 3-dB axial ratio bandwidth. To improve the 3-dB axial ratio, we introduced a pair of rectangular slots on the electric dipoles that can adjust the four ME-dipole modes for reducing the size of ground reflector. The antenna is designed on a RT/duroid® 5880LZ filled PTFE substrate with thickness of 1.27 mm and ϵr =2, tanδ = 0.0027.
