Abstract

A dual-band sleeve monopole antenna with the substrate-integrated coaxial line (SICL) technology is proposed in this paper. Both the radiation structure and the feeding network are modified from the SICL structure. The antenna provides dual-band operation for LoRa (Long Range Radio) applications covering 433 MHz and 868 MHz bands. This antenna operates as a quarter-wavelength monopole with practical omnidirectional radiation performance for each band. The antenna exhibits a gain of 2.0 dBi at 433 MHz with more than 90% radiation efficiency, and a gain of 1.7 dBi at 868 MHz with more than 90% radiation efficiency. The measured −10 dB impedance bandwidths are from

$393 \sim 450$

MHz and

$826 \sim 931$

MHz, respectively. A good agreement is observed between the measured and the simulated results, which demonstrates that the proposed scheme can be a possible candidate for LoRa applications.

利用基底集成同轴线技术设计双频平面套筒单极天线

本文提出了一种采用基底集成同轴线（SICL）技术的双频套筒单极子天线。辐射结构和馈电网络都是在 SICL 结构的基础上改进而来。该天线可为 LoRa（远程无线电）应用提供双频操作，覆盖 433 MHz 和 868 MHz 频段。该天线作为四分之一波长的单极子工作，在每个频段都具有实用的全向辐射性能。该天线在 433 MHz 波段的增益为 2.0 dBi，辐射效率超过 90%；在 868 MHz 波段的增益为 1.7 dBi，辐射效率超过 90%。测得的 -10 dB 阻抗带宽分别为 393 \sim 450$ MHz 和 826 \sim 931$ MHz。测量结果和模拟结果之间的一致性很好，这表明所提出的方案可以作为 LoRa 应用的候选方案。
