Abstract
An inclined-plane dual-horn structure is presented that couples energy from free-space to microstrip and back to free- space again. The structure consists of two back-to-back inclined planes that taper down to a common parallel-plate waveguide. The energy is fed from the parallel-plate waveguide to the microstrip using a transition that also serves as a power splitting network. The insertion loss from free-space to microstrip for the passive array is better than -2.5 dB from 30 to 47.5 GHz.
