Broadband Dual-Polarized Antenna Using Metasurface for Full-Duplex Applications

IEEE Antennas and Wireless Propagation Letters, 2021
In this letter, a broadband dual-polarized metasurface-based antenna is proposed for in-band full-duplex applications. The design concept exploits the wideband and low-profile features of a metasurface, as well as its structural symmetry to implement the

Broadband/Multiband Printed Antennas

IEICE Transactions on Communications, 2005
Broadening the frequency bandwidth of antennas has been one of the major subjects concerning antenna design technologies. Two of the major subjects for microstrip antennas, which appeared in the 1970s, have also been the broadening of the frequency bandwidth and the sharing of multifrequency bands. In this paper, we describe the broadband and multiband
