  • a transmission line is an electrical conductor for carrying radio and microwave frequency AC signals to and from the various components of a printed circuit board (e.g. in a filter circuit or electronic oscillator).
  • Standard wires and traces are not suitable for transmitting such high frequency signals because the energy tends to radiate off the conductor as radio/micro waves causing power losses.
  • radio and microwave frequency currents tend to reflect from discontinuities in the wire/trace (such as connectors and joints) and travel back down the conductor towards the source. This can prevent the signal from reaching its destination.
  • Transmission lines use special configurations and impedance matching to carry electromagnetic signals with fewer reflections and power losses. Common types of transmission line in modern circuits include the microstrip transmission line and the coplanar waveguide.
  • Figure 1 shows a microstrip transmission line 101 in perspective view. It consists of a conductive strip 102 (signal line) of length "I”, width "w” and thickness "t” separated from a ground plane 103 by a dielectric substrate 104 of thickness "h".

  • the electromagnetic wave carried by a coplanar waveguide 205 exists partly in the dielectric substrate 204 and partly in the air above it.
  • the signal can, however, be more closely confined to the dielectric substrate 204 by using a substrate thickness "h” of at least twice the width "w" of the signal line 202.

  • the conductive material used to form the electrodes 308a,b may also be used in the fabrication of the two-dimensional signal line 302. The multiple uses of the first 308a and second 308b electrodes help to reduce the cost and complexity of the present apparatus 307.
  • two-dimensional with respect to the signal line 302 may be taken to mean that the signal line 302 is formed from a conductive two-dimensional material typically comprising a single layer of atoms or molecules, examples of which include graphene and reduced graphene oxide.
