| Metamaterials is defined as the artificial composed structure with extraordinary physical properties. Orderly design to the key physical scale struction in material can break through some restrictions of natural law to gain super functions which can exceed natural regular properties. With the development of craft and production technology, artificial metamaterial develops from the theoretical analysis at the beginning to physical production, many different struction and application appear, for example, left-handed materials and Photonic Crystal. Metamaterial rapidly becomes the international hot research topic. Especially in the field of microwave antenna.Microstrip antenna has been widely used in wireless communication system.But at the same time, the exertion of microstrip antenna’s greater performance was restricted by its shortcomings.Like with its Working frequency is narrow and antenna’s gain is low.The new metamaterials provide a good method in antenna miniaturization and high gain etc as its singular characteristics. Then many existing problems can be solved with applying new metamaterials to microstrip antenna, so the research in this area is of great significance. In this paper, the main research works are as follows:Firstly detailed introduce the principle and analysis method about microstrip antennas,put forward the performance parameters and design parameters of microstrip antenna requirements. Secondly make simple introduction and analysis on left hand materials,based on the characteristics, design out of the CRLH structure of microstrip antenna.Thirdly introduce photonic crystals and makes a simple analysis on its features then study the application of photonic crystal in some characteristics of the microstrip antenna,A photonic crystal microstrip antenna are designed. At last, design a Photonic crystals with resonant ring heterogeneous antenna based on combination with the characteristics of photonic crystals and left-handed materials. |
