“…Te research direction of ultra-wideband antennas is mainly focused on the traditional bandwidth as well as on the antenna [5,6] size, where microstrip antennas have signifcant advantages over other forms of antennas [7]. In the literature [8], a tapered slot UWB antenna was designed to increase the bandwidth and reduce the area of the antenna by etching a series of rectangular slot lines, and the bandwidth was increased by 4.72 GHz compared to that without the etched slot lines.…”

The wearable ultra-wideband antenna that is appropriate for body area networks is designed and implemented in this article. Stepped circular radiation patches, microstrip feeders, and trapezoidal floors make up the majority of the antenna. Good bending qualities have been attained by using liquid crystal polymer, a flexible material, as a dielectric substrate. An antenna measuring 30 mm × 35 mm × 0.1 mm was designed with two C-shaped slots etched on it to achieve notch function in the 3.20–4.10 GHz and 5.19–5.98 GHz frequency bands. Its working frequency range was 1.96–11.61 GHz, and its specific absorption rate for the human body was less than 2 W/kg. The test findings demonstrate that ultra-wideband body area network systems can be implemented using the antenna impedance and radiation characteristics.

“…Furthermore, the design of EBG structures is very complex due to the uncertain dependence of the EBG properties on the unit cell parameters. Besides, performance and miniaturization are two major problems obtained in communication systems over UWB band [19]. That is, all wireless devices must have antennas that are as compact as feasible with high performance.…”

Ultra-wideband (UWB) technology has become influential among academic research and industry because of its vast application in the wireless world. However, several drawbacks have in UWB based antenna. To tackle this, EBG (Electromagnetic Band Gap) structures have proposed. Furthermore, the design of EBG structures is very complex due to the uncertain EBG properties dependence upon unit cell parameters. Therefore, to the optimal design of micro strip antenna for applications of UWB, EBG-PIO (pigeon inspired optimization) on the basis of micro strip patch antenna has been proposed to enhance micro strip antenna’s performance in terms of directivity, gain, bandwidth and efficiency. To select design parameters optimally, the PIO technique is proposed with substrate material of Rogers RT/Duroid 6010 with height h = 1.6 mm. Proposed antenna return loss remains –34.6 dB to cover applications of UWB (3.1–10.6 GHz). Also, results exhibited by both proposed technique and fabricated model-based antenna has outperformed than existing techniques regarding directivity, return loss, bandwidth, gain and radiation efficiency.

“…The property of space filling in a small area improves the electrical path length of the designed antenna [15]. Generally, the fractal geometry is applied into the patch and it is added in the antenna for designing the fractal antenna which is used to obtain the compact, small side lobe arrays and higher gain aerials [16]- [17]. However, the fractal antennas have different challenges such as radiation pattern enhancement, arbitrary frequency ratio, uniformity of impedance, polarization in multiband and directivity [18].…”

Microstrip antenna is broadly used in the modern communication system due to its significant features such as light weight, inexpensive, low profile, and ease of integration with radio frequency devices. The fractal shape is applied in antenna geometry to obtain the ultra-wideband antennas. In this paper, the sierpinski carpet fractal monopole antenna (SCFMA) is developed for base case, first iteration and second iteration to obtain the wideband based on its space filling and self-similar characteristics. The dimension of the monopole patch size is optimized to minimize the overall dimension of the fractal antenna. Moreover, the optimized planar structure is proposed using the microstrip line feed. The monopole antenna is mounted on the FR4 substrate with the thickness of 1.6 mm with loss tangent of 0.02 and relative permittivity of 4.4. The performance of this SCFMA is analyzed in terms of area, bandwidth, return loss, voltage standing wave ratio, radiation pattern and gain. The proposed fractal antenna achieves three different bandwidth ranges such as 2.6-4.0 GHz, 2.5-4.3 GHz and 2.4-4.4 GHz for base case, first and second iteration respectively. The proposed SCFMA is compared with existing fractal antennas to prove the efficiency of the SCFMA design. The area of the SCFMA is 25×20 mm<sup>2</sup>, which is less when compared to the existing fractal antennas.
