Abstract
This article presents a miniature printed Defected Ground Structure (DGS) antenna with a flawed ground structure for Ultra-Wide Band (UWB) implementations. The ultra-wideband antenna is created by fabricating it on an FR4 dielectric substrate that is 1.6 mm thick, has a dielectric constant (Ɛr) of 4.6, and has a tangential loss (ծ) of 0.02. The total area of the proposed antenna is about 30 x 28 mm2, and to improve its bandwidth, a defective ground plane has indeed been integrated into its design. The UWB antenna's total impedance bandwidth is 10 dB, and its operating spectrum runs from 3 to 10 GHz. The antenna has a substantial directivity of about 3.54 dBi over the whole of the requisite operating spectrum in every respect. In order to get an understanding of the design insight of the proposed antenna, the performance of the antenna was studied with the use of Smith charts. In terms of its radiation pattern and its directivity, the antenna has improved radiation properties. The overall performance of the antenna reveals that it has the potential to be a strong contender for usage in settings that need an ultra-wideband. This potential is shown by the fact that the antenna can transmit and receive signals across a broad frequency range.
