With the decades the advancement in technology is increased day by day. Advancement in technology generate so many software tools, procedures, simulation techniques to achieve the desired output. In antenna design, improvement of bandwidth is major key point. To achieve a better bandwidth with improved antenna parameters and calculate its graphical response is a key of this book. EMI radiation absorption is a major concern in today's scenario. With the increased number of mobile phone users the number of mobile towers are also increased. So the electromagnetic radiations are major concern, the work related to EMI radiation absorption can be further improved and the radiation mechanism can be further elaborated with much more efficient material used in design a patch antenna. Better bandwidth, high radiation efficiency and lower EMI radiation effects is a major challenge for design an antennas. Human health related to radiation effects and environment conditions will be improved, and achieve radiation less environment. So future work is also being carried to solve such issues.
