Abstract

This paper proposes two RF self-interference cancellation techniques. Their small form-factor enables full-duplex communication links for small -to-medium size portable devices and hence promotes the adoption of full-duplex in mass-market applications and next-generation standards, e.g. IEEE802.11 and 5G. Measured prototype implementations of an electrical balance duplexer and a dual-polarized antenna both achieve >50dB self-interference suppression at RF, operating in the ISM band at 2.45GHz.
