Abstract:
This paper describes the investigations conducted at the LEAT for wideband reflectarrays. Two antenna structures are presented. The first one is an offset reflectarray operating at the centre frequency of 94 GHz with a prolate horn as primary feed for wideband operation purpose. 17% gain bandwidth at 3 dB was obtained. The second one is a cosecans square folded reflectarary operating in the 76-81 GHz band.
