Abstract :
A new single-mode 1/spl times/3 equal-power divider using a substrate microprism and two waveguide expanders has been proposed and analyzed. Simulation results show that with appropriate phase-front tilt and field modification, equal power division and low insertion loss can be attained for a large branching angle. The effects of device parameters are also discussed to facilitate the design of the proposed equal-power divider. Because of not requiring extra regions of indices different from those of the waveguide and substrate, the proposed equal-power divider can be easily fabricated.
