Wideband tree shaped SIW antenna for 60GHz applications

摘要

Tree-shaped substrate Integrated Waveguide antenna is designed for short distance high data rate transformation RADAR applications. The tree shaped antenna is designed by using Rogers RT/Duriod 5880 Substrate and Coplanar waveguide transition is used as a transmission path. This Tree shaped antenna analyzed the characteristic like reflection coefficient, voltage standing wave ratio and electric fields are presented. Tree shaped antenna gives max magnitude of reflection coefficient -53.39dB at 60.1GHz and 1.007 as voltage standing wave ratio at 60GHz. This tree shaped antenna gives 9.96GHz as bandwidth. Dimensions of the tree shaped antenna structure is 5.9*4*0.508mm3. Due to its bandwidth, reflection coefficient, gain and dimensions this tree shaped antenna structure is full fill the requirements of millimeter wave application like wireless LAN and RADAR applications for today's society.
