The design and characterization of a single-layer wideband substrate integrated waveguide 3-dB standalone directional coupler are described. The device exhibits a bandwidth of 2 GHz, ranging from 10.7 to 12.7 GHz, and both return loss and isolation better than 15 dB. The coupler has been built using a TACONIC RF-35 A2 substrate. A very good agreement between simulations and experimental results is obtained.

Abstract
The design and characterization of a single-layer wideband substrate integrated waveguide 3-dB standalone directional coupler are described. The device exhibits a bandwidth of 2 GHz, ranging from 10.7 to 12.7 GHz, and both return loss and isolation better than 15 dB. The coupler has been built using a TACONIC RF-35 A2 substrate. A very good agreement between simulations and experimental results is obtained.File in questo prodotto:
