“…The pyramidal absorber can achieve an outstanding reflectivity (greater than 50 dB) over broadband frequencies and wide‐angle changes. [ 31 ] Pyramidal absorbers are versatile tools for managing EM radiation and are utilized in many different applications, such as the internal wall of anechoic chambers, radar systems, and communication systems.…”

In the era of the fifth generation (5G) and the Internet of Things (IoT), electromagnetic interference (EMI) poses a significant challenge. The rapid growth of wireless communication applications leads to increased electromagnetic (EM) pollution, which can have adverse health effects. To address this issue, electromagnetic absorbers (EMAs) play a critical role in eliminating EMI and reducing EM pollution between electronic devices. The focus is now on developing diverse microwave absorbing materials (MAMs) with different structures to cover a wide range of frequencies while remaining cost‐effective and effective at high angles of incidence radiation. This article comprehensively reviews EMAs, highlighting their design parameters and importance in achieving high‐efficiency absorption. The review covers absorber theory, structure, materials for various frequency ranges, and the mechanisms responsible for dissipating electromagnetic waves (EMWs). Analytical and numerical methods for modeling and analyzing EMAs are discussed, along with performance indicators and testing methods. The role of absorbers in different applications is explored, and emerging research directions for enhancing microwave absorbers are also highlighted.

“…The microstrip line is used as the feed antenna structure, and the coupling method is well known in terms of reducing the size of small antennas in mobile communications [37]. Microstrip antennas have the key advantages of being low-profile, easy to manufacture, lightweight, and have been widely used in wireless applications [38]. An antenna radiation scheme is essential for many communication applications, such as wireless communications and radar [39,40].…”

This paper describes the broadband monopole antenna refers to a signal wideband of the frequencies, which can be divided the signal into channels of the frequency bins. Aim this paper to design and development broadband monopole antenna. The monopole antenna was designed by adding slot to the radiated patch antenna with a single feed line, which reduced the size and the design complexity. A rectangular patch antenna was presented using feed line to decrease the ground plane with a suitable gap distance. The broadband monopole antenna was designed with a frequency range of 800 MHz -3 GHz, with Bandwidth 0.66 (dB), reflection coefficients and return loss. The frequency-dependent characteristic impedance was included. It can be used in various broadband applications in used commercially for various communication systems such as 4G (LTE), WiMAX and WLAN (LTE), remote sensing, biomedical, and mobile wireless. Apart from that, this technology is environment-friendly; an antenna which consists of reception and transmission. The antenna is simulated by using computer simulation (CST) software; using FR-4 substrate of 4.4 permittivity thickness 1.6 mm and loss tangent of 0.025. The measurement result is accepted with simulation result, proving the acceptable broadband operation for this proposed structure.

“…A CPW-fed slot antenna is realized by embedding a vertical stub with the T-shaped strip and a slit to the ground plane as reported in [22] for realizing dual-band operations. Various dual-band antenna designs include symmetrically introducing four slot stubs on lateral arms [23], by an asymmetric slots in F-shaped end patch [24], by backed ground plane with radial stub on two identical elements [25], by using two parallel monopoles, one curved and one fork-shaped [26], by monopole structure with two inverted U-shaped, L-shaped lateral stubs [27], with two rectangular parasitic elements and an I-shape grounded stub [28], by printed log-periodic dipole array (LPDA) [29], by slots and monopole antenna [30], and by employing meander line technique in [31]. A theoretical and experimental study of twin-slot multilayer CPW-fed antenna is reported in [32], and highly selective behavior and regulation of sharp variations of a discontinuous parallel-plate waveguide with a narrow rectangular ridge filled with axially anisotropic material identified using mode matching technique is achieved in [33].…”

A novel coplanar waveguide fed compact dual-band antenna for 2.5/5.7 GHz applications is presented in this paper. The above characteristics are obtained by carefully optimizing the slotted ground planes and meander short placed between the signal strip and one of the lateral ground planes. The proposed antenna has been designed on a substrate with dielectric constant 4.4, thickness 1.6 mm, and it occupies a small area of 18.2 × 20 mm 2. The experimental analysis shows 2 : 1 VSWR bandwidth up to 150 MHz and 370 MHz for 2.5 GHz and 5.7 GHz, respectively. Antenna radiation characteristics, including return loss, radiation pattern, radiation efficiency and gain are also validated with numerical simulation and experimental measurements.
