The modeling of characteristics of the patch antenna with non-uniform substrate metamaterial

Analysis of the effectiveness of metamaterials as a substrate of microstrip antennas for the purpose of providing broadband antenna while reducing the size and increasing the antenna gain are carried out in the report. As an example of the calculation of a microstrip antenna characteristics are given in which the substrate is a metamaterial unit cell in the form of nested open rings (SRR - split ring resonator). The resonant frequency of the resonator is determined by the length of the open rings, the size of the gap and the thickness of the rings. the basic laws of influence on the characteristics of microstrip antennas geometrical sizes of rings are obtained, the calculation results are summarized in the form of nomograms. The case of the planar antenna and conformal microstrip antenna located on a cylindrical surface is considered. Research are conducted by a specialized package FEKO.
