Technology scaling has enabled RF-CMOS circuits that operate in the millimeterwave frequency range (30 to 300GHz) where large bandwidths are available. These bandwidths can be exploited to increase data-rates of wireless communication links. Unfortunately, free-space path loss (FSPL) limits the operating distance of wireless systems at these frequencies. A 5-meter link at 120GHz has an FSPL as high as 88dB. Therefore such wireless links are feasible only with highly directive antennas. This work uses a directive channel instead. At mm-Wave frequencies, the directive channel can be a low-cost plastic fiber or hollow tube, made from PP, PS or Teflon. These directive channels will guide electromagnetic waves with low loss from TX to RX [1-4]. As such, RF communication through a plastic fiber becomes an interesting alternative and complements existing solutions like wireline copper or optical fibers. This paper
