Abstract

A 2×2 spatial combination structure has been proposed and designed in this paper. It based on two waveguide to mirostrip E-plane dual-probe structures connected with a broadband waveguide E-T branch symmetrically. The measured back-to-back insertion loss of 0.5 dB was achieved with a return loss of 10 dB at 3237GHz. With convenience of integrating solid-sate high power MMIC devices, this broadband low loss millimeter wave four-way symmetric microstrip integrated power dividing/combining network can realize millimeter solid-state high power combining with a high efficiency.
