提出了一种用于远程嵌入式无线监测的三维宽带无源谐波收发器。宽带性能是通过集成两个谐波中继器与相邻的中心频率。每个中继器由一个倍频器和共轭匹配的接收和发射曲折的微带天线。收发器通过接收2.35和2.85 GHz之间的f 1信号并以2*f 1重新辐射信号来工作，并针对低功耗操作进行了优化。该节点适合在λ/8.3（在2.4GHz）直径的球体内，重2.5g。在−18 dBm输入功率下，收发器的最大预期效率为5.6%。该收发器通过直接打印增材制造来制造。
A three-dimensional (3D) wideband passive harmonic transceiver for long-range embedded wireless monitoring is presented. The wideband performance is achieved by integrating two harmonic repeaters with adjacent centre frequencies. Each repeater consists of a frequency doubler and conjugate-matched receive and transmit meandered monopole antennas. The transceiver operates by receiving a signal at f 1 between 2.35 and 2.85 GHz and re-radiating a signal at 2*f 1 and is optimised for low-power operation. The node fits within a λ/8.3 (at 2.4 GHz) diameter sphere and weighs 2.5 g. The transceiver maximum expected efficiency is 5.6% at −18 dBm input power. The transceiver is fabricated via direct print additive manufacturing.
