This article describes the design of a passive Bi-band Fresnel reflectarray (20–30 GHz). It is focused on the design of the reflecting panel of the reflectarray. Two different primary feeds will be used at 20 and 30 GHz, respectively for demonstrating the proposed concept. Nevertheless, in the final design a switched primary feed will have to...

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 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...

Design of a folded reflectarray antenna (FRA) by phase only control to provide a cosecan squared beam pattern in elevation and a pencil-beam pattern in azimuth to detect objects on the ground, e.g., on runways. A very compact folded reflectarray antenna was fabricated and its radiation pattern over frequency was simulated. During the design...
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...
