We propose the design of a novel fractal antenna that is both unique and performance-driven. Two important antenna design features, miniaturization and wideband operation, are combined in this work. A ring-shaped antenna is designed using the well- known fractal geometry. is hybrid geometry is a fusion of meander and Koch curve shapes. e geometrical construction of the proposed antenna is compared to the standard Koch curve geometry. It is shown that combining the meander and Koch curve shapes increases the effective electrical length. e wider bandwidth is achieved by bringing the higher modes together. e overall dimensions of proposed meander Koch curve fractal ring antenna are 45 × 25 × 1.6mm 3 . e resonance frequency of the antenna is between 4.94 and 6.12 GHz (% BW � 21.83), which covers the entire 5GHz WLAN band. e prototype has been fabricated and experimentally verified. 1.Introduction e advancement of wireless communication technology has raised the bar for modern living. e sophisticated devices have brought a great degree of freedom to the conventional stationary working styles. e demand for data-hungry applications and multimedia streaming videos has given rise to the improved quality of service (QoS) in wireless communication systems. Antenna, an essential part of wireless communication system, must respond to the call of QoS improvement by enhancing its performance by aiming wide bandwidth, high gain, reduced return loss, omnidirectional radiation pattern, low cross-polarization, and reduced cost for fabrication. Fractal geometry has a long history; since its inception, fractals have been practically deployed in various technical fields. Mandelbrot introduced the term fractal from the Latin word “Fractus” in 1975 [1, 2]. Fractals shapes are nowhere differentiable as they are re- sultant of a recursive process. e increased bandwidth has been linked to fractal geometry’s self-similar, convoluted and jagged structures. Additionally, fractal geometry is used in antennas because of its unique properties, including small size and multiband/wideband behavior [3]. Numerous re- searchers have advocated incorporating fractal geometry into their antenna research. Several antenna geometries have been examined, including Koch, Cantor, Sierpinski, fractal tree, and Minkowski. In [4], an octagonal Fractal microstrip patch antenna with a superwideband bandwidth range of 10 GHz–50 GHz has been presented. For numerous appli- cations such as PCS, WLAN, WiFi, WiMax, and other communication systems, a Koch-like fractal curve has been proposed [5]. A Pythagorean tree was placed in a T-patch to form an ultrawideband (UWB) antenna [6]. Grounded coplanar waveguides have been used to enhance the bandwidth of conventional Sierpinski carpet antenna [7]. Additionally, various fractal shapes have been used to im- prove the properties of the dielectric resonator antennas [8–13]. Numerous fractal geometries have been combined to enhance the properties of fractal antennas such as Hindawi International Journal of Antennas and Propagation Volume 2022, Article ID 6136916, 8 pages https://doi.org/10.1155/2022/6136916
