3-Port T-junction SIW power divider for 60GHz applications

Abstract

In this article, V-band T- junction power divider is designed for 60GHz in the millimeter wave frequency range for upcoming new technologies in wireless communications. V- band T- junction power divider is designed by using substrate integrated waveguide technology and Coplanar waveguide transition is used as a transmission path. To design V-band T- junction power divider Rogers RT/Duriod 5880 Substrate material is used with a dielectric constant as 2.2 and electric loss tangent as 0.0009. This V-band T- junction power divider analyzed the characteristic like reflection coefficient, voltage standing wave ratio and electric fields results are presented. This power divider gives max reflection coefficient of −28.2dB and insertion loss as 3.1dB at 60GHz. This V-band T- junction power divider covers 32% of bandwidth in the unlicensed band of 57 to 64 GHz. Dimensions of the V-band T- junction power divider are 8∗6∗0.508mm3. Due to its dimensions and bandwidth this power divider is more suitable for millimeter wave applications like RADAR and 5G applications for today's need of society.
