bandwidth enhancement of electrically small antennas using meta-materials in HFSS software package

I want to get the same results as the attached research paper have mentioned in the thesis of it which is attached with this request. This paper is a base paper for my research topic so I need to get the results close to the mentioned in the base paper. Base paper author have done the analysis of Z-antenna, stub-antenna and canopy antenna for the low Q values and to improve radiation efficiencies. I need to get this results for myself to do further research on it. Tools required: The software used for this analysis is Ansoft HFSS 11.0.
