Abstract

Performance of microstrip circular patch antenna is determinable from the dielectric substrate used between the patch and the groundplane. An FR4 epoxy dielectric substrate is one of the materials which is frequently used to implement the microstrip patch antenna. This paper presents a performance analysis of microstrip circular patch antenna composed of artificial dielectric material (ADM). Here, the ADM is made of an FR4 epoxy dielectric substrate as the host material which is modified by incorporating a number of thin conductor wires into inside of the dielectric substrate. Meanwhile, a conventional microstrip circular patch antenna is also designed as comparison by using the same dielectric substrate without any modification. The characterization results show that the resonant frequency of microstrip circular patch antennas made of ADM with 82 and 110 thin conductor wires are 16.19% and 23.17% lower than of the conventional microstrip circular patch antenna, respectively. Whilst the–10dB working bandwidths of microstrip circular patch antenna made of ADM with 82 and 110 thin conductor wires are around 72.9MHz narrower around 43.4% than of the conventional microstrip circular patch antenna. In addition, the gains of microstrip circular patch antenna made of ADM with 82 and 110 thin conductor wires are 5.54dBi and 6.1dBi, respectively, where these are relatively higher than of the conventional microstrip circular patch antenna which has the gain of 5.24dBi.

人造介电材料微带圆形贴片天线的性能分析

微带圆形贴片天线的性能取决于贴片与接地面之间使用的介电基板。FR4环氧介电基板是实现微带贴片天线的常用材料之一。本文对人造介电材料(ADM)构成的微带圆形贴片天线进行了性能分析。在这里，ADM是由FR4环氧树脂介电基板作为主体材料制成的，通过在介电基板内部加入一些细导体线来改性。同时，本文还设计了一种传统的微带圆形贴片天线作为对比，该天线采用相同的介质基片而不作任何修改。表征结果表明，与传统微带圆形贴片天线相比，采用细导线82和110的ADM制成的微带圆形贴片天线的谐振频率分别降低了16.19%和23.17%。与传统微带圆形贴片天线相比，采用82和110细导体导线的ADM制成的微带圆形贴片天线在10db工作带宽约为72.9MHz，约窄43.4%。此外，采用82和110细导体导线的ADM制成的微带圆形贴片天线的增益分别为5.54dBi和6.1dBi，相对于传统的微带圆形贴片天线的增益为5.24dBi来说，这是相对较高的。
