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.
