  • Abstract
    This letter proposes a novel shrinking technology of ultrawideband (UWB) antennas among the conventional various ultrawideband antenna structures. An eye-shaped UWB antenna was designed to extend the lower frequency band under a limited antenna size. The operating band (1.2 ~ 4.5 GHz) can reach a fractional bandwidth of as high as 142%. The overall dimension, including the ground area, can be shrunk to 0.027λ02. The group delay is nearly constant to ensure minimal distortion and dispersion. From the measurement, the antenna radiation pattern is close to omnidirectional and is suitable for general applications.
