| Abstract | ||
| This work presents the design and construction of a ground plane semicircular slot based on planar antennas for wideband applications, including sub-6 GHz 5G wireless and WiFi. The radiating patch is designed to have a U shape with a transmission line feed. Beneath the radiating patch, a semicircle-Defected Ground Structure (DGS) is carved to control the bandwidth and minimize the size of the antenna. A two T-shaped stub construction one on the top of the other is affixed in the center of the U-shaped radiating area to enable wideband operation. The antenna functions as a Wide-Band Antenna (WBA) if the width of transverse portion of the top T construction is equal to the width of U shape. Additionally, shortening and altering the transverse sector of the upper T structure is equal to creating a band-stop filter with an adjustable resonant frequency that regulates the antenna's two operational bands. The design has a small footprint of where denotes the free space wavelength, peak gain, and efficiency of about and , respectively. When the length of the top T- shape , the antenna acts as a WBA with frequency band from . Moreover, a time-domain analysis highlights the antenna's responsiveness and adaptability to wireless applications by providing insightful information on how it reacts to transitory signals | ||
