Design of a Substrate Integrated Waveguide Slots Antenna in W Band for Aircraft Radar Application

The paper presents a design of a SIW (Substrate Integrated Waveguide) slot’s antenna in W band for a sense-and-avoid radar module to tackle an emerging need of security during landing and take-off for small aircrafts. This work is developed inside the ODESSA project, funded by the European Union. The antenna was formed by 7 slots etched on the top face of a SIW structure designed on a Rogers RO3003G2 substrate. Simulation and experimental results, for both cases with and without radome, are presented inside 76-80 GHz frequency range. Good performances are obtained for efficiency and realized gain which were the main objectives of this work
