This article describes the principle of combining circular or annular patches with C-patches on a Fresnel reflector that introduces radiation pattern diversity according to the polarization. Patches were designed to perform a 180° phase difference of the reflection phase between two orthogonal polarizations for a monopulse antenna purpose. ©...

This paper describes a compact broadband (73-80 GHz) mm-Wave front-end used for FOD detection application. The design philosophy of our system is to have several low-profile, low-cost mm-Wave sensors placed along the runway. Tests were conducted on the small airport of Aix Les Milles (south of France). High sensitivity and simultaneous objects...

Based on a folded reflectarray antenna, a three-beam antenna is investigated using dielectric rods as primary feed placed in open-ended waveguides for obtaining an optimal illumination on the reflector. The performances for a dielectric rod and a combination of three rods are investigated using Ansoft HFSS software. In a first step, dielectric...

This paper presents the results of FOD measurements conducted using a broadband 78 GHz radar sensor. Previous studies with a short-range setup up to 30 m showed promising results. However, to meet the requirements of the intended application, the range has to be increased significantly. As for all radar systems, the range can be extended by...
