A W-band miniature power divider based on E-faced-folded magic-T junction

Abstract

A novel design of W-band power divider using E-faced-folded waveguide magic-T junction to realize the miniaturization is proposed in this paper. A stepped regular triangular prism and the stepped impedance transformer are utilized in order to obtain excellent performance. Besides, the performance of the E-faced-folded magic-T power divider is also improved by using short planes. The measured results show that the insertion loss of the power divider is better than 0.6dB and the return loss is better than 15dB. The measured average E-H isolation is better than 30dB from 92GHz to 100GHz range.
