A Compact Self-Decoupled In-Band Full-Duplex Monopole Antenna Based on Common- and Differential-Mode Theory
Published on 2025-07-10 by Yuejian Li, Yao Hu, Yu Luo @MDPI
Abstract: In-band full-duplex (IBFD) technology has attracted significant attention for its potential to double the spectral efficiency by enabling a simultaneous transmission and reception over the same frequency channel. However, achieving high isolation between closely spaced transmit and receive paths remains a critical challenge. In this paper, a novel compact co-polarized monopole antenna with self-decoupling capability is proposed based on common-mode/differential-mode (CM/DM) theory. By innovative[...]
Our summary: A novel compact monopole antenna design based on common-mode/differential-mode theory enables high isolation for in-band full-duplex technology, achieving over 20 dB isolation within the operating band.
