A dual-polarized high-isolation dielectric resonator antenna for full-duplex massive multiple-input and multiple output is proposed. The design integrates cross-polarized dual ports, utilizing two distinct mechanisms, probe feeding and aperture feeding, to enhance isolation performance. The beamforming capability and Tx-to-Rx port and beam-level isolation with monostatic and bistatic array configurations are studied. The proposed antenna element demonstrates a realized gain of 8.6 dB and a remarkable radiation efficiency of 97.7% at 3.5 GHz. In sample 1×8 array configurations, the design delivers an effective beam steering range from -60 to +60 degrees, with an average directivity and 3dB-beamwidth of 14.9 dB and 16.2 degrees, respectively. When deployed in a monostatic full-duplex array, the proposed structure achieves an average Tx-Rx port isolation of 53.8 dB. Moreover, adopting a bistatic array configuration can further enhance the average beam-level isolation to 73.4 dB, with peak beam-level isolation reaching up to 94.4 dB.
