In this paper, a tri-band metamaterial (MTM) loaded compact monopole antenna is proposed. In the first step of design procedure, a rectangular monopole antenna is improved by replacing the corresponding rectangular patch with a ring resonator. As a result, the first obtained operating frequency is decreased from 2.95 to 2.46 GHz. Then, this operating frequency is reduced to 2.02 GHz utilizing an MTM geometry in the antenna structure. The geometry parameters of the proposed antenna are optimized to provide the applicability for 3G, WLAN, and WiMAX applications. The impedance bandwidths of 600, 1080, and 220 MHz are obtained at 2.02–2.62, 3.48–4.56, and 5.12–5.34 GHz, respectively. Moreover, the equivalent circuit of the proposed antenna has been extracted. The proposed equivalent circuit model is validated through a comparison with corresponding simulation results. The proposed antenna is compact, low profile, via-less, and provides easy fabrication. Considering the first resonance frequency, a compactness of 32% is achieved in comparison to the corresponding unloaded monopole antenna.

“…Varamini et al [23] presented the microstrip antenna with Sierpinski carpet (MASC) to enhance the matching and bandwidth and the Minkowski fractal was used to maximize the antenna area. The permeability and permittivity were obtained to split ring resonator (i.e., metamaterial) by using the reflection/transmission method.…”

“…The SCFMA design obtains three different bandwidths for three iterations 2.6-4.0 GHz, 2.5-4.3 GHz and 2.4-4.4 GHz respectively. Table 3 shows the comparative analysis of the proposed SCFMA with existing fractal antennas such as monopole fractal antenna [21], square patch MPA [22], MASC [23], Koch-Minkowski hybrid slot based MPA [24], fractal antenna [25] and MMFHA [26]. The SCFMA design achieves lesser size than the existing fractal antennas by optimizing the structure of the monopole patch while designing the fractal structures.…”

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.

This paper presents a polarization‐insensitive and ultra‐broadband metamaterial absorber (UMMA), which has higher absorption throughout the whole X‐band. The UMMA unit cell consists of a metal film and a multilayer‐cross‐cone structure separated by a dielectric layer. The calculation result shows that the UMMA's absorptivity is greater than 96% in the entire X‐band (8–12 GHz) and the UMMA is polarization‐insensitive for normal incident wave. Moreover, the absorption rate is also more than 80% in X‐band when the incident angle is less than 56° for TE polarization wave. The electric field, magnetic field, and surface current distribution of the UMMA are analyzed to study its absorption mechanism. The influences of different key structural parameters on the absorber are also discussed, including the arm length and arm width of the bottom and top of the cross‐cone structure and the number of layers of the cross metal, consequently, a set of optimized design parameters is obtained. The proposed UMMA has a higher absorption rate in the entire X‐band, the UMMA can be used in electromagnetic stealth, electromagnetic shielding, secret detection and so on.
