Abstract:

One of the methods for optimizing the radiation characteristics of microstrip antennas is using metamaterial as substrate and superstrate. In this research, a rectangular microstrip antenna with circular polarization and conical pattern is designed at 2.2 GHz frequency. For creating circular polarization cutting corner method is used and to create conical pattern, 4 array rectangular microstrip patch antennas are used and each antenna is feeded by microstrip line and whole of structure is feeded by a 50 Ω SMA connector. To improve the radiation characteristics and optimize the dimensions of antenna, a 10×10 aray layer of metamaterial is used as substrate and Then the antenna has been made. The metamaterial parameters such as Permeability (µ) and Permittivity (ε) is extracted by Nicolson-Rose method. The simulation results show that the antenna dimensions is decreased 30% and bandwidth and gain of the antenna are increased 17% and 45% respectively. All the simulation process for antenna designation is implemented in HFSS 18.2 software.
