基于磁负超材料的低互耦天线阵列设计
Design of Low Mutual Coupling Antenna Array Based on Single-Negative Magnetic Metamaterial
摘要
Abstract
A novel single-negative magnetic metamaterial is proposed and its electromagnetic property is analyzed by using HFSS and Matlab.The results show that the proposed metamaterial has wonderful magnetic negative characteristic.Taking advantage of the bandstop characteristic of the proposed metamaterial in the magnetic negative band resonance, a coaxial fed two element microstrip antenna array operating in 3 GHz is designed.By adding the proposed metamaterial,the designed antenna array realizes a mutual coupling reduction of 12.1 dB.The distance between the antenna units is only λ/10 (λ is the operating wavelength in free space), and the far-field radiation performance of antennas is improved.Therefore, the proposed metamaterial has broad application prospects in the esign of compact high performance antenna arrays.关键词
