Year: 2024
Type: article
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 393~450 MHz and 826~931 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.
