Abstract

A Substrate Integrated Waveguide (SIW) 3dB directional coupler is presented. It is implemented on the glossy material (Rogers R04350), with substrate thickness 1.524 mm, loss tangent of 0.04 and relative permittivity 3.66. Different via profiles are investigated. It conducts coupling coefficient of 3 dB with some losses contributed from the structure. The via profile conducts the change in the bandwidth of the coupler which can help in tuning the coupler bandwidth.
