A novel transition from a grounded‐coplanar waveguide to a substrate integrated‐waveguide (SIW) is presented featuring a fully planar bias tee for the development of 60 GHz radio‐over‐fibre photonic transmitters for indoor applications. The transition is intended to serve as a connection between a 60 GHz photodiode chip and SIW antennas suitable for indoor data distribution. Simulations show that in the whole 57–64 GHz communication band, the return loss (RL) is at least 15 dB, whereas the insertion loss (IL), is < 0.9 dB. Measurements of a back‐to‐back configuration confirm the numerical results, with a IL of ∼2 dB and a RL > 12 dB.
