Design of Integrated Duplexing and Multi-Band Filtering Slot Antennas

IEEE Access, 2020
In this paper, a duplexing antenna and two multi-band filtering antennas using resonator loaded slot are presented. The loaded slot can be flexibly designed as a dual-band or a tri-band antenna by changing the number of the loaded resonator.
