Errata or comment

A novel millimetre-wave quasi-optical low-loss power divider based on the dipole antenna is presented. This dipole antenna array is inserted in the E-plane of the rectangular waveguide to implement the power-dividing function. A Ka-band four-way passive power combiner is designed, fabricated and measured. The measured results show that the minimum insertion loss is about 0.4 dB from 32.1 to 34 GHz, whereas the return loss is less than 10 dB from 31.5 to 35.9 GHz. The measured results agree with the simulated ones closely.
