초록
This paper proposes a frequency reconfigurable dual-band passive 360° reflection-type phase shifter (RTPS) for fifth-generation (5G) applications. The proposed phase shifter provides a full 360° phase shift range in multiple 5G new radio (NR) communication bands—n261 (27.5–28.35 GHz) and n260 (37–40 GHz)—using a transformer-based switchable inductor. The proposed transformer-based switchable inductor allows the operating frequency bands to be changed for achieving maximum phase shift range. Consequently, the proposed RPTS achieves a full 360° phase shift range with average insertion losses of 7.65 ± 2.08 and 7.03 ± 0.15 dB at 28 and 39 GHz, respectively. To the best of our knowledge, the proposed RTPS is the first dual-band RTPS to achieve a 360° phase shift in 5G NR FR2 applications.
