A Multiband Antenna Stacked with Novel Metamaterial SCSRR and CSSRR for WiMAX/WLAN Applications

Abstract

This paper presents an innovative method for the design of a triple band meta-mode antenna. This unique design of antenna finds application in a particular frequency band of WLAN and WiMAX. This antenna comprises of a square complimentary split ring resonator (SCSRR), a coaxial feed, and two symmetrical comb shaped split ring resonators (CSSRR). The metamaterial unit cell SCSRR independently gains control in the band range 3.15–3.25 GHz (WiMAX), whereas two symmetrical CSSRR unit cell controls the band in the ranges 3.91–4.01 GHz and 5.79–5.94 GHz (WLAN). This design methodology and the study of the suggested unit cells structure are reviewed in classical waveguide medium theory. The antenna has a miniaturized size of only 0.213λ0 × 0.192λ0 × 0.0271λ0 (20 × 18 × 2.54 mm3, where λ0 is the free space wavelength at 3.2 GHz). The detailed dimension analysis of the proposed antenna and its radiation efficiency are also presented in this paper. All the necessary simulations are carried out in High Frequency Structure Simulator (HFSS) 13.0 tool.

A Microstrip Antenna Using I-Shaped Metamaterial Superstrate with Enhanced Gain for Multiband Wireless Systems

“…A multi-layered SRR was staked over the patch antenna [ 26 ]. A multiband antenna with metamaterial was proposed in [ 27 ] for WiMax/WLAN applications. A dual-band compact SRR shaped antenna was proposed and investigated in [ 28 ].…”

A Frequency Reconfigurable Folded Antenna for Cognitive Radio Communication

“…Many efforts have been exerted to achieve multiband behaviour and many techniques have been employed to fulfill the demands of recent wireless communication technologies. Some of the employed techniques to achieve multiband behaviour are a fractal structure [ 9 , 10 ], a complementary split ring resonator metamaterial [ 11 ], a window grille cross-structure [ 12 ], a meandered offset-feed [ 13 ], a split ring resonator and inverted F slots [ 14 ], a bowtie slot patch [ 15 ], and DGS and DMS [ 16 , 17 ]. An additional capability that can be possibly integrated with the multiband behaviour of the antenna is the reconfigurability which has a vital role in the accomplishment of cognitive radio applications, and it can be carried out using PIN diodes [ 18 , 19 , 20 , 21 ], varactor diodes [ 22 ], lumped capacitors [ 23 , 24 ], and RF MEMS [ 25 ].…”

Coaxial Pin-fed Multiband Fractal Square Antenna for Satellite Applications

“…This is due to their ability to tailor both permittivity and permeability independently, which allows them to interact with electromagnetic waves in a variety of ways, resulting in multiple bands. [7,8] exhibit metamaterial-based multiband antennas comprising complementary split-ring resonators. A multiband antenna that is loaded with parasitic components is presented in [9].…”
