Modeling and Simulation Metamaterail Effects on Radiation Pattern Of Micro strip Antenna

摘要

This paper presents effect of metamaterial on the radiation pattern of microstrip antenna at 60GHz band. A new design of metamaterial antenna based Square Split Ring Resonator and a conventional microstrip patch antenna both designed using gallium arsenate dialectical substrate to study the effect of ration pattern of antenna. The metamaterial antenna is made by using a single layer of metamaterial reflecting surface which is design from array of squared split ring resonator (SRR) printed on a GaAs dielectric. The height of reflecting surface is adjusted to improve the radiation pattern performance. The results show that the gain of the antenna radiation pattern with metamaterial reflecting surface is increased by 1.2dB compared with conventional patch antenna without the metamaterial superstrate without distorting the antenna resonance frequency. High Frequency Structure Simulator (HFSS) was used to simulate and analysis the metamaterial substrate and antenna configurations.
