Abstract

A new high isolation slot array antenna offering dual-polarization and high isolation for 5G in-band full-duplex (IBFD) applications is presented. The single-layer structure consists of series-fed SIW slot arrays oriented in a cross-shaped setup. Also, the proposed design exploits dual-differential feeding to achieve-10 dB matching from 23.2 GHz to 25.3 GHz and the isolation between activated and passive ports is around 70 dB. The maximum simulated realized gain is around 13.8 dBi while the simulated cross-polarizations are well below 30 dB or lower from the main beam maximum. To the best knowledge of the authors, no similar antenna configuration has been previously reported offering high isolation in the K-band, which can enable high-data-rate transfer for in-band full-duplex systems.
