Résumé

This article presents a first step towards the design of a multi-feed circularly polarized EBG antenna which serves as a reflector focal array. The circular polarization is obtained by using a multilayer meander lines polarizer, placed above a linearly polarized EBG antenna. The details of the antenna and the polarizer are given and the "transparent" effect of the polarizer on the antenna feed performance is emphasized after comparing the performance with and without the polarizer. The designed antenna is used to illuminate a reflector antenna for RX Ka-band space applications [29.5 - 30] GHz, and the coverage performance will be shown.
