Review on Band-Notching Techniques for Ultrawideband Antenna

摘要

In this paper, different band-notching techniques for ultrawideband antenna have been reviewed briefly. The bandwidth of the notched band directly depends on the longitudinal length of the slot, and the shape of the slot has no effect. Each resonator design corresponds to one frequency notch in an antenna. Moreover, a designer may incorporate more than one technique in a single design to achieve band notches. Two antennas under reference [1, 2] have been implemented.
