Euclidean and fractal terms are mathematically and physically important terms in antenna design, but rarely reported studies had discussed these terms together in antenna design in their texts. This paper first gives an overview of Euclidean and fractal antennas with useful and satisfactory facts. Four printed slot antennas are then studied using Euclidean slot shapes printed in the ground plane with and without Euclidean patches using FR4 substrate. These antennas are employed to investigate their suitability as simple alternatives to complicated fractal geometries and their specific formulas. Parametric analyses with feedline lengths and patch scaling aspects are adopted to generate single, dual, and multiband responses. These parametric studies provide different outcomes and choices for antenna electrical specifications suitable for various wireless applications. It is clear that inserting Euclidean patches to the printed slot in the ground plane influence inducing multiple operating bands as similar as multiband fractal antenna, but without using specific formulas or complicated outlines. All proposed antennas have low-profile topologies, good compactness, and more competitive electrical specifications than many reported fractal antennas. The simulations of the proposed printed slot antennas are in good compatibility with the measurements.

“…The antenna reported greater gain values at (2.39 and 3.77) GHz, with performance efficiency (82.54 and 75.11)% respectively. Noteworthy that the dimension of the antenna is significantly greater than other antennas indicated in [48] knowing that the encouraging results obtained with this model, though, compensate the large scale. In addition, the small difference in S11 value was due to the manufacturing defects, SMA connector errors, and soldering effects (see Figure 4(b)).…”

“…Hence, the antenna can be a good candidate for wearable and wireless applications. For 2.42 GHz wireless local-area-network (WLAN) and 3.78 GHz worldwide interoperability for microwave access (WiMAX) applications, a dual-band versatile antenna was built by Kantharia et al [48] in which the fractal arrangement utilizing coplanar waveguide (CPW) is proposed (see Figure 4(a)). The application of fractal geometry contributes to enhancing impedance bandwidth and radiation efficiency.…”

This study investigates the performance of flexible, wideband antennas with high gain properties. The high gain feature can often be obtained by positioning a reflector in the same planes as the adjacent radiator. For flexibility, this survey discusses the antennas that were printed on the flexible substrate materials. Based on these properties, the antenna can be recognized in a variety of wireless applications, including wireless local-area-network (WLAN), Worldwide Interoperability for microwave access (WI-Max), wireless body area network (WBAN), and radio frequency identification (RFID), as well as wearable applications. The high-gain antennas are compact radio wave-based antennas that provide precise radio transmission management. Such antennas deliver more energy to the receiver, increasing the frequency of the received signal. By gathering more power, high-gain antennas may emit signals quicker. Furthermore, because directional antennas broadcast fewer signals from the main wave, interference may be greatly minimized. Finally, this article identifies the role of lightweight high gain flexible antennas in terms of their size, substrate materials, design, and feeding mechanisms, all of which can affect bandwidth, gain, radiation efficiency, and other important factors.

“…Desai et al [16] present a flexible coplanar waveguide antenna using polyethylene terephthalate as a dielectric substrate and compare the performance of this antenna with antennas made of other materials but with the same structure. Kantharia et al [17] proposed a fractal dual-band flexible antenna based on the coplanar waveguide structure, where the antenna uses FR-4 as the dielectric substrate and obtains excellent performance in terms of bandwidth and radiation efficiency using the fractal geometry.…”

This paper presents a multiband planar antenna with a third-order toroidal coupling structure that has potential applications in mobile communications. The antenna is fed using a coplanar waveguide structure. The radiating body model of the antenna is obtained by scaling and nesting twice in equal proportions based on a first-order toroid. The above patch was printed on a 42 × 55 × 0.1 mm3 polyimide flexible dielectric substrate. This article explores the effect of bending in different directions on the antenna performance and explores the effect of coupling with the human body on the antenna S11. The antenna was simulated using a high-frequency structure simulator and measured in an electromagnetic microwave darkroom. The simulation results of the antenna match well with the measured results, and the maximum gain of its band coverage is 4.39 dBi. The antenna can cover the frequency bands of TD-LTE (B-TrunC) (1.447–1.467 GHz), LTE42/43 (3.4–3.8 GHz), WiMAX (3.3–3.8 GHz), 5G band n78 (3.4–3.8 GHz), WLAN (5.15–5.35 GHz), 5G (5.725–5.825 GHz), and other commercial bands.
