| Abstract: | In this paper,several patch antennas based on different periodic cell photonic bandgap structures are proposed.The method based on finite element was used to analyze those different antennas,and we get some results about the influence of different photonic bandgap structure to the patch antenna by compared with each other.We found that its input return losses were reduced,the radiation efficiency was higher and its gain was improved in the patch antenna by adding the PBG structure.And it also contains that the shape and number of periodic cell influenced the properties. |
