This paper proposes a broadband single-ended line-to-waveguide transition that covers the 240–300 click here GHz band.The transition comprises a tapered grounded coplanar waveguide (GCPW) feed line, inserted from the narrow wall of the waveguide exciting a modified V-shaped patch located at the center of the waveguide.Broadband operation is achieved via multiple resonances of the modified V-shaped patch, a double-stacked rectangular patch, and cavity within the multi-layer substrates.

The transition geometries are optimized via electromagnetic simulations using the finite element method.The transition design is successful within fabrication limitations in coq-clear 100 ubiquinol the terahertz frequency band.Subsequent evaluations of transition performance are conducted through measurements and simulations.

Experimental results show a bandwidth below −10 dB for S11 spanning 71.5 GHz.Furthermore, the measured insertion loss remains consistent at 2.

5 dB at the center frequency of 275 GHz.
