Abstract

The high permittivity of dielectric material is required to lower the resonant frequency of the microstrip circular patch antenna. An FR4 epoxy dielectric substrate frequently applied for the antenna deployment results in high losses due to its inherent characteristics, hence this leads to lower the efficiency. In this paper, an experimental approach to lower the resonant frequency of microstrip circular patch antenna by using artificial dielectric material (ADM) made of a modified styrofoam is proposed. By inserting a number of thin conductor wires into the styrofoam as a host material, the relative permittivity of host material could be increased. The electric fields distribution for TMz resonant mode in the microstrip circular patch antenna becomes a reference for placing the thin conductor wires. The result of experimental approach shows that the ADM made of 110 pieces 0.5mm diameter thin conductor wires inserted into a styrofoam could significantly lower the resonant frequency of conventional microstrip circular patch antenna around 48% from 1832.3MHz to 951.2MHz. In other term, there is an increase of effective relative permittivity up to 270%.

微带圆形贴片天线的ADM降频实验方法

为了降低微带圆形贴片天线的谐振频率，需要介质材料具有较高的介电常数。经常应用于天线部署的FR4环氧介电基板由于其固有特性导致损耗大，从而导致效率降低。本文提出了一种利用改性聚苯乙烯泡沫塑料制成的人工介电材料(ADM)降低微带圆形贴片天线谐振频率的实验方法。通过在泡沫聚苯乙烯作为主体材料中插入一些细导线，可以提高主体材料的相对介电常数。微带圆形贴片天线中TMz谐振模式的电场分布为细导体导线的布置提供了参考。实验结果表明，将110根直径0.5mm的细导体导线插入聚苯乙烯泡沫塑料中，可以将传统微带圆形贴片天线的谐振频率从1832.3MHz显著降低到951.2MHz，降低幅度约为48%。换句话说，有效相对介电常数增加了270%。
