    This paper describes three RF self-interference reduction techniques for full-duplex wireless links, which specifically target integration in compact radios. Concretely, a self-interference cancelling front-end, a dual-polarized antenna, and an electrical balance duplexer are proposed. Each technique offers specific benefits in terms of implementation density, selfinterference rejection, bandwidth and flexibility. Depending on their characteristics, they can be adopted in different next generation full-duplex applications and standards. All concepts are prototyped, and achieve at least 45dB of self-interference reduction over more than 10MHz bandwidth. Index Terms—Full-duplex wireless, self-interference, polarized antenna, electrical balance duplexer, analog cancellation.
