Met material loaded rectangular monopole antenna with ultra-wideband applications

Abstract

A planar-rectangular monopole antenna with split ring resonators (SRR) is presented in this article. The objective of the proposed antenna is to obtain the frequency notch characteristic in the wide operating band. Frequency notch characteristics are attained by placing, split ring resonators and the defected ground structure (CSRR) on the top and bottom sides of the FR4 substrate respectively. The proposed antenna works in the band between 2.5-9.5GHz and 12.58-20GHz and remaining band is notched. This metamaterial loaded antenna and its analysis is carried out through unit-cell analysis and the characteristics such as permittivity and permeability have been plotted. The proposed antenna shows the characteristics of high gain, size reduction and high radiation efficiency.
