Abstract

This chapter addresses an approach to achieve the ultra-wideband (UWB) spectrum as well as discusses the phenomena of frequency interference within UWB antennas. The antenna consists of a hexagonal-shaped structure printed over FR4 substrate. For bandwidth improvement, defected ground structure (DGS) was first introduced, and, secondly, a stub was added in the feeding strip to achieve a larger bandwidth. To achieve the frequency band-notched characteristics, a half hexagonal slot was etched on the radiator, which creates a notch at 5.2 GHz, and then by introducing a full hexagonal slot, another rejected band was produced at 10 GHz. The outcomes also confirm the proposed UWB antenna design can achieve superior dual band-notch performance at desired frequency bands.
