Advances in reconfigurable antennas for wireless communications

This paper presents an overview of the recent advances in frequency, polarization and pattern reconfigurable antennas for wireless communications. In particular, it reports our latest progress in this research field, including a wideband to narrowband frequency tunable antenna, a dual-band polarization reconfigurable antenna, a beam-steering quasi-Yagi dipole antenna and a beam-steering antenna array based on reconfigurable defected microstrip structure (RDMS).
