Abstract

In the present study, the suitability of Ni-Co spinel ferrites as dielectric substrate for microstrip patch antenna has been reconnoitered in X-band frequency range. The scrutinized spinel ferrites with chemical composition Ni1. xCoxFe2O4(x=0.00,0.30,0.60,0.90) were synthesized using Pechini's sol gel method. For the present study, Ansoft Designer SV2 was used to design and analyze the microstrip patch antenna. Simulation of antenna was done at resonant frequency of 10.02 GHz, which makes this research to find application in military and surveillance. Firstly, the antenna dimensions were calculated using resonant frequency and electromagnetic properties of the compositions. The antenna output parameters such as return loss, bandwidth, VSWR (Voltage Standing Wave Ratio), Smith Chart and radiation pattern were subsequently analyzed by the simulation Based on the analysis, Ni-Co ferrite Ni0.l Co0.9Fe2O4has come out to be the best alternative out of the studied compositions for its possible usage as efficient dielectric substrate in microstrip patch antenna in 8.2 – 12.4 GHz frequency range.

Ni0.1CO0.9Fe2O4尖晶石铁氧体作为x波段微带贴片天线的有前途的磁介质衬底

在x波段范围内，对镍钴尖晶石铁氧体作为微带贴片天线介质衬底的适用性进行了研究。化学成分为Ni1的尖晶石铁素体。采用Pechini溶胶-凝胶法合成xCoxFe2O4(x=0.00,0.30,0.60,0.90)。本研究采用Ansoft Designer SV2软件对微带贴片天线进行设计和分析。在10.02 GHz谐振频率下对天线进行了仿真，验证了该研究在军事和监视领域的应用前景。首先，根据各成分的谐振频率和电磁特性计算天线尺寸;随后通过仿真分析了天线输出参数如回波损耗、带宽、驻波电压比、史密斯图和辐射方向图等。由于co0.9 fe2o4在8.2 ~ 12.4 GHz频率范围内可作为微带贴片天线的高效介电衬底，因此是研究组合物中最好的选择。
