Abstract

This paper presents a rectangular microstrip patch antenna with EBG structure. The combination of the rectangular microstrip patch antenna fabricated on the top of the substrate Rogers RO3003 with Electromagnetic Band Gap (EBG) structures at the ground plane is proposed to investigate the metamaterial characteristics in antenna design for satellite application. The patch antenna along with the EBG structure is designed to resonate at 7.3 GHz. Simulations and measurements have been carried out to verify the performance of EBG structures in patch antenna. All the simulation and measurement work is done by using Computer Simulation Technology Microwave Studio (CST-MWS) and Vector Network Analyzer (VNA) respectively. Metamaterial characteristics which exhibit negative permittivity and permeability of the proposed EBG structures have been verified using Nicolson-Ross-Weir (NRW) method. As a result of combining the rectangular patch with EBG structure, the bandwidth of the antenna has been increased by 39.63% and the size of the antenna reduced by 22.38% compared to the antenna without EBG. The return loss also met the specification of -10 dB cut off.

EBG结构矩形微带贴片天线

提出了一种具有EBG结构的矩形微带贴片天线。为了研究卫星天线设计中的超材料特性，提出了将Rogers RO3003基板顶部的矩形微带贴片天线与地平面的电磁带隙(EBG)结构相结合。贴片天线和EBG结构的谐振频率为7.3 GHz。通过仿真和测量验证了EBG结构在贴片天线中的性能。所有的仿真和测量工作分别由计算机仿真技术微波工作室(CST-MWS)和矢量网络分析仪(VNA)完成。采用Nicolson-Ross-Weir (NRW)方法验证了所提出的EBG结构具有负介电常数和磁导率的超材料特性。将矩形贴片与EBG结构相结合后，天线的带宽比无EBG结构时提高了39.63%，天线尺寸减小了22.38%。回波损耗也满足- 10db截止的要求。
