Abstract
This article presents a new design of a compact fractal antenna that operates across various wireless communication applications with wideband functionality. With a peak gain of 6.8 dB and a radiation efficiency ranging from 91% to 94%, the designed antenna operates in the frequency range of 3.2–7.5 GHz. The antenna consists of a rectangular radiator with integrated rectangular slots on one side of an FR4 substrate, while a partial ground plane is etched on the other side. The fabricated prototype was tested and measured. The results present a good agreement with the simulated results. The results presented by this antenna demonstrate high competitiveness for wireless communication applications such as Wi-Fi and WLAN and presents a promising solution to meet the increasing demand for compact and high-performance wireless communication devices. Additionally, the antenna has a small size of only 34 × 30 × 1.6 mm3, making it suitable for applications where space is limited. Overall, this paper provides an innovative and efficient design that offers excellent performance and is suitable for various wireless communication applications.
