“…It should be mentioned that a relatively long microstrip feedline increases the total size of antenna that is important for input impedance matching. The overall size of the antenna can become smaller by using a matching network in substitution of present feedline [18].…”

“…In this design, throughout the current flow on the meander line and the circular patch, the shunt and series inductances can be obtained, and between the two adjacent lines, the shunt capacitance (C R ) has been formed. The various amount of ZOR frequency can be obtained by changing the length and width of unit cell which results in different amounts of L R and C R according to [18] …”

In this work, a compact and broadband and planar monopole antenna consists of one unit cell of epsilon negative transmission line (ENG TL) is proposed. A disc-shaped monopole antenna is implemented at 2.45 GHz resonance frequency for 2.4 GHz applications. A 50 Ω microstrip line is used as a feedline and element of the antenna has 0.1λ 0 of diameter. The size of the antenna is reduced to 0.32λ 0 × 0.32λ 0 , and the -10 dB fractional bandwidth is improved to 12.8% due to using metamaterial transmission line. Prototype antenna is fabricated and tested, and the measured results are compared to the simulated results using Ansoft HFSS.

“…The emergent interest in metamaterial due to its left-handed properties [1][2][3][4][5] has led to its application in many potential devices, such as antenna [6,7], filter [8], absorber [9,10], cloaking [11,12], etc. The research of metamaterial absorber (MMA) is definitely significant in radar applications, such as stealth technology, reduction in specific absorption rate (SAR) in mobile phones and medical devices [13,14], etc.…”

Abstract-A new design has been proposed for a single layer polarization-insensitive dual-band metamaterial absorber at C and X bands. The proposed structure consists of a periodic arrangement of a circular resonator embedded in a square resonator. A commercially available FR4 dielectric has been used as a substrate with metallic grounded bottom and imprints on the other side. This structure resonates at 5.5 GHz and 8.9 GHz with absorptivity of 99.8% and 99.97%, respectively. It exhibits polarization-insensitive behaviour for Transverse Electric and Transverse Magnetic polarization under oblique and normal angles of incidence. The field distributions have been studied for better understanding of the absorption mechanism. The fabricated structure has been tested, and the experimental results are similar to the simulated ones. This polarization-insensitive metamaterial absorber with its ease of design and nearly unity absorption can be used for radar applications.

“…To satisfy this trend, a variety of antennas have been engineered with metamaterials (MTMs) [1] and metamaterial-inspired constructs [2,3] in order to improve their performances such as miniaturization [4][5][6][7], high efficiency [8][9][10], enhanced bandwidth [11,12], high gain [13,14], and reconfigurability [15,16].…”

Abstract-A new family of metamaterial-inspired monopole antennas designed for GPS operation is reported. By adding a simple Split-Ring Resonator (SRR) into the near-field region of a monopole antenna resonating at 2.45 GHz, we have created a second resonance situated in the L1-band (f = 1, 537 for example) lower than the monopole's one. At this new resonance, the directivity of the structure was enhanced and its profile was reduced. Four SRR-configurations were considered depending on the orientation of the slot into the resonator. The structure was first optimized by adjusting the resonator size and the coupling distance between it and the monopole. Next, the directivity of the structure was improved by adjusting both the SRR-slot position and the coupling distance. Finally, the optimized structure in terms of size and directivity was realized and characterized.
