Abstract

In this paper, an E-band four-channel power dividing/combining network is designed based on H-plane 3dB waveguide directional couplers. Firstly, the waveguide H-plane 3dB directional coupler with working frequency of 71~78GHz is designed by HFSS to achieve low loss and high isolation. According to the phase relationship of each port of the coupler, the topology of the power dividing/combining network is worked out, and then the HFSS simulation analysis model for the whole network is established. On the basis of simulation analysis and optimization, a prototype of the four-channel power dividing/combining network of the E-band were manufactured. A back-to-back testing scheme, where a one-fourth dividing network and a four-in-one combining network is jointed together, is adopted to facilitate the testing work. The measured results show that the overall insertion loss of the power dividing/combining network is less than 2.2dB, with a typical value of 1.7dB, in the frequency range of 72~77GHz.
