Computers & Electrical Engineering, 2020
A novel compact Coplanar Wave Guide (CPW)-fed metamaterial (MTM)-inspired multiband antenna is designed for Wireless Local Area Network (WLAN), C-Band, Universal Mobile Telecommunication System (UMTS) and Worldwide Interoperability for Microwave Access (WiMAX) applications. The new multiband antenna with the dimensions of 40 × 40 × 0.8 mm 3 is fabricated on FR4 substrate. It consists of circular shaped Split Ring Resonator (SRR) with five rings and resonates at 2.10 GHz (UMTS), 2.9 GHz (WLAN), 3.5 GHz (WiMAX), 4.5 GHz (C-band), 5.7 GHz (WLAN) and 6.5 GHz (WLAN-IEEE 802.11ax). Parametric studies are performed on a number of metallic rings, height of the CPW-fed ground plane and different substrate materials for the proposed penta-ring SRR. A prototype antenna is fabricated and the results are measured to examine the simulated results. The measurement of the radiation pattern shows an omnidirectional pattern in H-plane and a dipole like pattern in E-plane.

2020
In this paper we present a novel miniaturized dual-band patch antenna based on the metamaterial concept. Complementary split ring resonators, which are excellent structures for miniaturization; along with spiral resonators are used in the proposed design for obtaining a compact dual-band patch antenna. The original patch which is designed to resonate at 2.86 GHz is found to resonate at 1.92 GHz & 2.44 GHz when loaded with three pairs of square complementary ring resonators. Further its ground is also loaded with a spiral resonator yielding a relatively compact antenna structure. The present design has been tuned to the above two bands which finds application in PCS and WLAN applications. The percentage of miniaturization obtained is 51.4 % & 17.6 % respectively. The proposed antenna achieves an efficiency of 80% & 37% in the two bands of resonance.

We present characteristics of microstrip patch antennas on metamaterial substrates loaded with complementary split-ring resonators (CSRRs). The proposed antenna utilizes CSRRs in the ground plane altering the effective medium parameters of the substrate. To characterize the performance of the CSRR loaded microstrip antenna, the metamaterial substrate has been modeled as an effective medium with extracted constitutive parameters. Simulation results were verified by experimental results. The experimental results confirm that the CSRR loaded patch antenna achieves size reduction as well as bandwidth improvement.

In this work, we propose the design of metamaterial inspired compact circular patch antennas loaded with complementary split-ring resonators (CSRRs) for ISM band operation. CSRRs have been incorporated horizontally inside the dielectric. The various models of CSRR loaded antennas with different patch radius are produced and are evaluated numerically with Ansoft HFSS software. The results of the suggested antenna designs are presented that reveal a comparable impedance match and radiation characteristics with those of a normal patch antenna without CSRR. The proposed antennas yield high levels of miniaturization and similar performance to the conventional patch antenna at the 2.45GHz.

The turn ratio, coupling space between sections, and substrate permittivity effects on spilt ring resonator (SRR) are investigated. The analysis of the presented SRR with respect to the effects of substrate and number of gaps per ring to further characterize its peculiarities is experimented with miniaturized capability as our intent. Six different SRRs were designed with different turn ratios, and the sixth is rectangular microstrip patch centre-inserted. Different numbers and gap sizes are cut on the SRRs while the gap spacing between the conductors of the SRR was varied to determine their effects taking cognizance of the effects of different substrates. The designs were investigated numerically using 3D finite integration technique commercial EM solver, and the resulting designs were prototyped and subsequently measured. Findings indicate that the reflection coefficient of the MSRR with centre-inserted patch antenna is better compared to MSRR without the patch antenna irrespectiv...
