Title : Linearized series structure design of metamaterial antenna applications with high characteristics performance


The uniqueness of metamaterial becomes attention in science on the structure and materials to obtain the negative refractive index properties. Applications in the world of metamaterial technology are always intensified to obtain high material media work effectiveness through improving the quality of performance such as antenna components. Application of this structure can increase the profile of an antenna technology. The influence of the characteristics and optimization of the structure and material determines the work effectiveness of a device. This research was carried out by applying a series combination from 1 until 4 hexagonal, square and circular ring resonator (SRR) structures operated at a maximum frequency of 9GHz in the Ultra Wide Band category, while the experiment is underway to investigate its properties. The results showed that the metamaterial is double negative, with the highest negative refractive index in the combination of SRR-H structures and a resonant frequency shift of 1.73GHz to a frequency of as low as 1.97GHz. Combination structure 4, SRR-H has the highest antenna work performance with the width of the working frequency band width1.09-9.00GHz and the highest power loss is -55.91dB. Increased hexagonal, square, and circle antenna structure gain has a difference of around 5% with isotropic radiation patterns. Appropriate antenna radiation occurs at a maximum SRR-H structure of 4.63dBi on a 5.97GHz frequency
