Abstract

This article presents a compact size circularly polarized substrate integrated waveguide (SIW) based wideband antenna array that serves industrial, scientific, and medical (ISM) band applications. A coplanar waveguide (CPW) technique is used to ensure the antenna size compactness. The proposed antenna is fabricated on a low-profile Rogers RT6002 substrate with a dielectric constant of 2.94, tanδ of 0.0012 and an approximate height of 0.76mm. The proposed design covers the frequency range from 2.15 GHz to 3.63 GHz (60.4%) while the axial ratio has a 3 dB bandwidth covering from 2.19 GHz to 2.51 GHz (13%) at the operating band of 2.45 GHz. The antenna is miniaturized and has a size of about 46.50 × 29 × 0.76 mm. The simulation and experimental results are taken into consideration and there is a good promise between them. Hence, the antenna is a suitable applicant to be utilized for the applications in the ISM band.

摘要

本文介绍了一种基于紧凑型圆极化基片集成波导（SIW）的宽带天线阵列，适用于工业、科学和医疗（ISM）频段应用。采用共面波导（CPW）技术以确保天线尺寸紧凑。所提出的天线制作在低剖面的罗杰斯RT6002基片上，其介电常数为2.94，损耗角正切为0.0012，近似高度为0.76mm。所提出的设计覆盖2.15 GHz至3.63 GHz的频率范围（60.4%），而在2.45 GHz工作频段，轴比的3 dB带宽覆盖2.19 GHz至2.51 GHz（13%）。该天线实现了小型化，尺寸约为46.50×29×0.76 mm。考虑了仿真和实验结果，两者之间有良好的一致性。因此，该天线是适用于ISM频段应用的合适候选者。
