Abstract: [EN] An eight-port wide-band multiple-input multiple-output (MIMO) antenna is presented for base stations applications. The antenna is composed by four unit cells (2×2) separated by a cross-shaped isolating block with a total size of 220×220×28 mm ` (2.42¿×2.42¿×0.3¿ , at central frequency f=fc=3.3 GHz). The unit cell is defined by a square cavity-backed antenna fed with two I-shaped crossed dipoles. The antenna provides 8 independent ports with 21.5 dB of minimum isolation and an impedance bandwidth (S11<br />This work has been supported by the Spanish Ministry of Science and Innovation (Ministerio de Ciencia e Innovacion) under project PID2019-107885GB-C32.
