BiQuad MIMO Antenna System for UAV Mobile Base Station in n28 5G NR Band

A two-element BiQuad MIMO antenna system working in the n28 5G NR band is presented as a mobile base station mounted on UAV. The proposed antenna system can provide an optimized solution for rapid deployment in disaster-affected areas to provide a temporary communication network for rescue operations. The two BiQuad antenna elements are oriented towards ±45^◦ with respect to the broad sight direction to enhance the communication coverage region.
