Abstract :
A W-band quasi-optical power combiner based on waveguide lens with wide band, low insert-loss, and good combining efficiency is designed in this paper. The quasi-optical power combiner consists of two E-plane sectoral horns with focusing a waveguide lenses for distribution of signals. By adjusting and optimizing parameters of the power combiner in CST continuously, an adequate performance can be obtained. The return-loss characteristic for CST model of the quasi-optical power combiner is better than 18.5 dB and the insert-loss is lower than 0.06 dB over the frequency band from 91.8 GHz to 97.1 GHz.
