Abstract
Substrate Integrated Waveguide (SIW) technology allows the construction of several different types of planar antennas. However, when integrated with active components which require DC biasing, it is often the case that the top and ground plane are short-circuited due to the existence of the metallic vias that connect them. Corrugated SIW (CSIW) is proposed to remedy this. CSIW completely swaps out the vias in favour of quarter-wavelength microstrip stubs called “corrugations”. With the absence of a connecting conducting surface between the top and ground plane, the possibility of a shot-circuit is eliminated while still maintaining TE10 type boundary conditions. In this project, a configuration of Microstrip fed CSIW Slot Antenna is proposed and studied. The slots are designed in the top of the CSIW to achieve radiation by interrupting the current flow. The antenna works in the 77 GHz frequency range and is verified and evaluated by Ansys HFSS simulation.
