CPW fed miniaturized dual-band short-ended metamaterial antenna using modified split-ring resonator for wireless application

Abstract

A miniaturized dual‐band metamaterial (MTM) antenna has been designed in this article. The designed coplanar waveguide fed antenna has composed of inner split‐ring resonator and an outer open ring resonator with rectangular stub. The series parameter of the antenna is used to determine the zeroth order resonance frequency due to short‐ended boundary condition. The whole size of proposed structure is 20 × 25.5 mm2. This MTM antenna exhibits dual‐band operation at 3.17 GHz (3.1–3.22 GHz) and 5.39 GHz (5.27–5.47 GHz). The proposed MTM structure achieves measured peak gain of 0.71 and 1.89 dB at 3.17 and 5.39 GHz, respectively. The proposed antenna can be used for recent radio communication in form of S‐band application and Wi‐MAX.

A metamaterial loaded hybrid fractal multiband antenna for wireless applications with frequency band reconfigurability characteristics

“…Another methodology of metamaterial loading have garnered noteworthy attention in designing of multiple resonating smart antenna due to its specific characteristics like as negative dielectric parameters (permeability and permittivity), negative refractive index, electrically small in size etc. In this concern, many metamaterial inspired multiband antenna have been designed and reported in literature [19][20][21][22][23][24][25]. Xu et al [19] employed a gain-enhanced resonant antennas with implementation of twodimensional CSRRs loaded CRLH TL (composite Right/ Left-handed transmission line).…”

Bandwidth and gain‐enhanced composite right/left‐handed antenna for ultra‐wideband applications

“…As a key part of UWB system, an UWB antenna is expected to possess the features such as compact size, large bandwidth, high radiation efficiency, high realized gain and low group delay. Metamaterials (MTMs) have been widely used in antenna design applications due to their unique electromagnetic properties . As compared to the conventional half‐wavelength antennas, MTM‐based antennas have the advantage of being more compact in size due to a special feature called zeroth‐order resonance (ZOR).…”
