A New Design of Terahertz Suspended Microstrip

We proposed a new design of terahertz suspended microstrip applied in the terahertz power combining network. For the simulation, the reflection loss less than 20dB is achieved for this suspended microstrip in frequency band from 0.18 THz to 0.22 THz. A new fabricating method is proposed for the suspended microstrips, and the measurement showed that the average insertion loss is below 0.5 dB within the operating frequency range.
