Abstract

A reconfigurable inductorless negative-refractive-index transmission-line (NRI-TL) metamaterial phase shifter for sub-6 GHz 5G antenna applications is proposed. The design consists of a microstrip transmission line loaded both in series and in parallel with varactor diodes to provide continuous tuning of the phase of the transmitted signal by varying the bias voltage applied to the varactors, without the need for variable inductor components. The total measured differential phase shift is 190° at 3.2 GHz, with a measured insertion loss of 1.5–2.7 dB in the frequency range of 3.2–3.6 GHz, when the biasing voltage of the varactors is varied between 0 and 7 V. The total size of the microstrip NRI-TL phase shifter is 19.4 mm × 24 mm. The proposed reconfigurable phase shifter has been incorporated into the feeding network of a two-element antenna array to demonstrate its use in beam-steering applications. The measured results for the reconfigurable array show good impedance matching between 3 and 3.35 GHz for all biasing values, allowing continuous beam steering over a scanning range of 60°.

用于5G天线波束导向应用的可重构无电感负折射率传输在线超材料移相器

提出了一种用于sub-6 GHz 5G天线的可重构无电感负折射率在线传输(NRI-TL)超材料移相器。该设计由微带传输线串联和并联加载变容二极管，通过改变施加在变容二极管上的偏置电压来连续调谐传输信号的相位，而不需要可变电感元件。当变容管的偏置电压在0 ~ 7 V之间变化时，在3.2 GHz频率范围内，测量到的总差相移为190°，插入损耗为1.5 ~ 2.7 dB。微带NRI-TL移相器的总尺寸为19.4 mm × 24 mm。所提出的可重构移相器已被整合到双元天线阵列的馈电网络中，以演示其在波束导向应用中的应用。可重构阵列的测量结果表明，所有偏置值在3和3.35 GHz之间具有良好的阻抗匹配，可以在60°的扫描范围内实现连续波束转向。
