Abstract

A broadband transition device based on substrate integrated waveguide structureis proposed in this letter. With the novel guide wave structure, electromagnetic waves could be limited in the rectangular cavity formed by two rows of metal hole and the upper and lower metal border to achieve low losseffect. Combined with the advantages of that multiple impedance transformer, it can broaden the bandwidth of microwave circuits. A broadband transition is designed to cover the 33GHz-50GHz band showing a return loss of 10dB and insertion loss of 0.68dB. The measurement error is within an allowable range and consistents with the simulation results. The proposed transition meets the design requirements for broadband and low-loss.
