摘要
Two designs for three-port orthogonally polarized antennas using dipole antennas and half-slot antennas are proposed in this letter. Each of the antennas constitutes three mutually perpendicular radiating elements to achieve good isolation and low antenna signal correlation between ports. The antennas are fabricated on FR4 epoxy boards and experimental results are provided. Experimental results show that the antennas resonate at 2.55 GHz and have a mutual coupling of less than - 18 dB between elements. In addition, experimental results for the diversity performance and the multiple-input-multiple-output (MIMO) channel capacity are also provided for these antennas and these show that the proposed antennas offer good diversity gain and the channel capacity can be increased by as much as three times by using these antennas.
