https://doi.org/10.5515/KJKIEES.2025.36.3.231

This paper presents a reflective-type phase shifter (RTPS) and the effect of an electroless nickel immersion gold (ENIG) surface finish on its insertion loss. The former is commonly used in transmit- and reflect-array designs for electrical beam steering. Its design is simple and robust, providing a high phase shift and low insertion loss. However, if proper attention is not paid to the surface finish applied on copper traces, higher-than-expected insertion losses can occur. This was demonstrated through simulations, which were compared with me...

The UWB technology of the IEEE 802.15.4z standard provides excellent performance for indoor positioning based on ultra-wideband. However, the ranging accuracy and the measurement time duration required for ranging vary depending on the two-way ranging method or physical layer parameters used. Although the ranging accuracy and measurement time are important parameters in indoor positioning, research on them to date is insufficient. Therefore, in this study, we first analyzed the ranging accuracy according to the SS-TWR and DS-TWR methods, as sug...
