Optimization and validation of W-band waveguide-to-microstrip broadside probe transition
The optimization and validation of broadside mounted design for W-band (75-110GHz) waveguide-to-microstrip probe transition are presented. The substrate of microstrip was Aluminum (εr=9.9) and WR-10 waveguide is used in this transition. The dimensions of the transition have been optimized for full b...
