Bandwidth and Return Loss Amelioration by Integrating Left Handed Metamaterial at 1.989 GHz

Author proposed a new design of meta-material to provide advancement into the factors of the rectangular microstrip patch antenna (RMPA) at the resonant frequency of 1.989 GHz. In this work enhancement of the antenna parameters are provided by using a meta-material structure of the proposed design. The antenna parameter like Bandwidth and return loss get a large amelioration while other factors like efficiency and directivity are also improved slightly. This design of meta-material is loaded over the patch antenna to give an enhancement into the antenna factors. CST (Computer Simulation Technique) software is used in to the whole design and analysis process. By using the proposed design the bandwidth of antenna is increased up to 31.1 MHz from 19.1 MHz(appx. 82%), Return loss is reduced up to -53.7 from -10.88(appx. 490%) and efficiency is enhanced by 6%(52 to 58%). After the designing process we prove the structure used is a meta-material structure with the help of NRW approach and excel software.
